It was part of the original Logo programming language developed by Wally Feurzig and Seymour Papert in 1966. Imagine a robotic turtle starting at (0, 0) in the x-y plane. Give it the command turtle.forward(15), and it moves (on-screen!) 15 pixels in the direction it is facing, drawing a line as it moves. Give it the command turtle.left(25), and it rotates in-place 25 degrees clockwise. By combining together these and similar commands, intricate shapes and pictures can easily be drawn. ----- turtle.py This module is an extended reimplementation of turtle.py from the Python standard distribution up to Python 2.5. (See: http://www.python.org) It tries to keep the merits of turtle.py and to be (nearly) 100% compatible with it. This means in the first place to enable the learning programmer to use all the commands, classes and methods interactively when using the module from within IDLE run with the -n switch. Roughly it has the following features added: - Better animation of the turtle movements, especially of turning the turtle. So the turtles can more easily be used as a visual feedback instrument by the (beginning) programmer. - Different turtle shapes, gif-images as turtle shapes, user defined and user controllable turtle shapes, among them compound (multicolored) shapes. Turtle shapes can be stretched and tilted, which makes turtles very versatile geometrical objects. - Fine control over turtle movement and screen updates via delay(), and enhanced tracer() and speed() methods. - Aliases for the most commonly used commands, like fd for forward etc., following the early Logo traditions. This reduces the boring work of typing long sequences of commands, which often occur in a natural way when kids try to program fancy pictures on their first encounter with turtle graphics. - Turtles now have an undo()-method with configurable undo-buffer. - Some simple commands/methods for creating event driven programs (mouse-, key-, timer-events). Especially useful for programming games. - A scrollable Canvas class. The default scrollable Canvas can be extended interactively as needed while playing around with the turtle(s). - A TurtleScreen class with methods controlling background color or background image, window and canvas size and other properties of the TurtleScreen. - There is a method, setworldcoordinates(), to install a user defined coordinate-system for the TurtleScreen. - The implementation uses a 2-vector class named Vec2D, derived from tuple. This class is public, so it can be imported by the application programmer, which makes certain types of computations very natural and compact. - Appearance of the TurtleScreen and the Turtles at startup/import can be configured by means of a turtle.cfg configuration file. The default configuration mimics the appearance of the old turtle module. - If configured appropriately the module reads in docstrings from a docstring dictionary in some different language, supplied separately and replaces the English ones by those read in. There is a utility function write_docstringdict() to write a dictionary with the original (English) docstrings to disc, so it can serve as a template for translations. Behind the scenes there are some features included with possible extensions in in mind. These will be commented and documented elsewhere.

Example: >>> color("black", "red") >>> begin_fill() >>> circle(60) >>> end_fill() end_poly() Stop recording the vertices of a polygon. No argument. Stop recording the vertices of a polygon. Current turtle position is last point of polygon. This will be connected with the first point. Example: >>> end_poly() exitonclick() Go into mainloop until the mouse is clicked. No arguments. Bind bye() method to mouseclick on TurtleScreen. If "using_IDLE" - value in configuration dictionary is False (default value), enter mainloop. If IDLE with -n switch (no subprocess) is used, this value should be set to True in turtle.cfg. In this case IDLE's mainloop is active also for the client script. This is a method of the Screen-class and not available for TurtleScreen instances. Example: >>> exitonclick() fd(distance) Move the turtle forward by the specified distance. Aliases: forward | fd Argument: distance -- a number (integer or float) Move the turtle forward by the specified distance, in the direction the turtle is headed. Example: >>> position() (0.00, 0.00) >>> forward(25) >>> position() (25.00,0.00) >>> forward(-75) >>> position() (-50.00,0.00) fillcolor(*args) Return or set the fillcolor. Arguments: Four input formats are allowed: - fillcolor() Return the current fillcolor as color specification string, possibly in hex-number format (see example). May be used as input to another color/pencolor/fillcolor call. - fillcolor(colorstring) s is a Tk color specification string, such as "red" or "yellow" - fillcolor((r, g, b)) *a tuple* of r, g, and b, which represent, an RGB color, and each of r, g, and b are in the range 0..colormode, where colormode is either 1.0 or 255 - fillcolor(r, g, b) r, g, and b represent an RGB color, and each of r, g, and b are in the range 0..colormode If turtleshape is a polygon, the interior of that polygon is drawn with the newly set fillcolor. Example: >>> fillcolor('violet') >>> col = pencolor() >>> fillcolor(col) >>> fillcolor(0, .5, 0) filling() Return fillstate (True if filling, False else). No argument. Example: >>> begin_fill() >>> if filling(): pensize(5) else: pensize(3) forward(distance) Move the turtle forward by the specified distance. Aliases: forward | fd Argument: distance -- a number (integer or float) Move the turtle forward by the specified distance, in the direction the turtle is headed.

Example: >>> p = get_poly() >>> register_shape("myFavouriteShape", p) get_shapepoly() Return the current shape polygon as tuple of coordinate pairs. No argument. Examples: >>> shape("square") >>> shapetransform(4, -1, 0, 2) >>> get_shapepoly() ((50, -20), (30, 20), (-50, 20), (-30, -20)) getcanvas() Return the Canvas of this TurtleScreen. No argument. Example: >>> cv = getcanvas() >>> cv getpen() Return the Turtleobject itself. No argument. Only reasonable use: as a function to return the 'anonymous turtle': Example: >>> pet = getturtle() >>> pet.fd(50) >>> pet >>> turtles() [] getscreen() Return the TurtleScreen object, the turtle is drawing on. No argument. Return the TurtleScreen object, the turtle is drawing on. So TurtleScreen-methods can be called for that object. Example: >>> ts = getscreen() >>> ts >>> ts.bgcolor("pink") getshapes() Return a list of names of all currently available turtle shapes. No argument. Example: >>> getshapes() ['arrow', 'blank', 'circle', ... , 'turtle'] getturtle() Return the Turtleobject itself. No argument. Only reasonable use: as a function to return the 'anonymous turtle': Example: >>> pet = getturtle() >>> pet.fd(50) >>> pet >>> turtles() [] goto(x, y=None) Move turtle to an absolute position. Aliases: setpos | setposition | goto: Arguments: x -- a number or a pair/vector of numbers y -- a number None call: goto(x, y) # two coordinates --or: goto((x, y)) # a pair (tuple) of coordinates --or: goto(vec) # e.g. as returned by pos() Move turtle to an absolute position. If the pen is down, a line will be drawn. The turtle's orientation does not change. Example: >>> tp = pos() >>> tp (0.00, 0.00) >>> setpos(60,30) >>> pos() (60.00,30.00) >>> setpos((20,80)) >>> pos() (20.00,80.00) >>> setpos(tp) >>> pos() (0.00,0.00) heading() Return the turtle's current heading. No arguments. Example: >>> left(67) >>> heading() 67.0 hideturtle() Makes the turtle invisible. Aliases: hideturtle | ht No argument. It's a good idea to do this while you're in the middle of a complicated drawing, because hiding the turtle speeds up the drawing observably. Example: >>> hideturtle() home() Move turtle to the origin - coordinates (0,0). No arguments. Move turtle to the origin - coordinates (0,0) and set its heading to its start-orientation (which depends on mode). Example: >>> home() ht() Makes the turtle invisible. Aliases: hideturtle | ht No argument. It's a good idea to do this while you're in the middle of a complicated drawing, because hiding the turtle speeds up the drawing observably. Example: >>> hideturtle() isdown() Return True if pen is down, False if it's up. No argument. Example: >>> penup() >>> isdown() False >>> pendown() >>> isdown() True isvisible() Return True if the Turtle is shown, False if it's hidden. No argument. Example: >>> hideturtle() >>> print isvisible(): False left(angle) Turn turtle left by angle units. Aliases: left | lt Argument: angle -- a number (integer or float) Turn turtle left by angle units. (Units are by default degrees, but can be set via the degrees() and radians() functions.) Angle orientation depends on mode. (See this.) Example: >>> heading() 22.0 >>> left(45) >>> heading() 67.0 listen(xdummy=None, ydummy=None) Set focus on TurtleScreen (in order to collect key-events) No arguments. Dummy arguments are provided in order to be able to pass listen to the onclick method. Example: >>> listen() lt(angle) Turn turtle left by angle units. Aliases: left | lt Argument: angle -- a number (integer or float) Turn turtle left by angle units. (Units are by default degrees, but can be set via the degrees() and radians() functions.) Angle orientation depends on mode. (See this.) Example: >>> heading() 22.0 >>> left(45) >>> heading() 67.0 mainloop() Starts event loop - calling Tkinter's mainloop function. No argument. Must be last statement in a turtle graphics program. Must NOT be used if a script is run from within IDLE in -n mode (No subprocess) - for interactive use of turtle graphics. Example: >>> mainloop() mode(mode=None) Set turtle-mode ('standard', 'logo' or 'world') and perform reset. Optional argument: mode -- on of the strings 'standard', 'logo' or 'world' Mode 'standard' is compatible with turtle.py. Mode 'logo' is compatible with most Logo-Turtle-Graphics. Mode 'world' uses userdefined 'worldcoordinates'. *Attention*: in this mode angles appear distorted if x/y unit-ratio doesn't equal 1. If mode is not given, return the current mode. Mode Initial turtle heading positive angles ------------|-------------------------|------------------- 'standard' to the right (east) counterclockwise 'logo' upward (north) clockwise Examples: >>> mode('logo') # resets turtle heading to north >>> mode() 'logo' numinput(title, prompt, default=None, minval=None, maxval=None) Pop up a dialog window for input of a number. Arguments: title is the title of the dialog window, prompt is a text mostly describing what numerical information to input. default: default value minval: minimum value for imput maxval: maximum value for input The number input must be in the range minval .. maxval if these are given. If not, a hint is issued and the dialog remains open for correction. Return the number input. If the dialog is canceled, return None. Example: >>> numinput("Poker", "Your stakes:", 1000, minval=10, maxval=10000) onclick(fun, btn=1, add=None) Bind fun to mouse-click event on this turtle on canvas. Arguments: fun -- a function with two arguments, to which will be assigned the coordinates of the clicked point on the canvas. num -- number of the mouse-button defaults to 1 (left mouse button). add -- True or False. If True, new binding will be added, otherwise it will replace a former binding. Example for the anonymous turtle, i. e. the procedural way: >>> def turn(x, y): left(360) >>> onclick(turn) # Now clicking into the turtle will turn it. >>> onclick(None) # event-binding will be removed ondrag(fun, btn=1, add=None) Bind fun to mouse-move event on this turtle on canvas. Arguments: fun -- a function with two arguments, to which will be assigned the coordinates of the clicked point on the canvas. num -- number of the mouse-button defaults to 1 (left mouse button).

Moreover one or more of these attributes can be provided as keyword-arguments. This can be used to set several pen attributes in one statement. Examples: >>> pen(fillcolor="black", pencolor="red", pensize=10) >>> pen() {'pensize': 10, 'shown': True, 'resizemode': 'auto', 'outline': 1, 'pencolor': 'red', 'pendown': True, 'fillcolor': 'black', 'stretchfactor': (1,1), 'speed': 3, 'shearfactor': 0.0} >>> penstate=pen() >>> color("yellow","") >>> penup() >>> pen() {'pensize': 10, 'shown': True, 'resizemode': 'auto', 'outline': 1, 'pencolor': 'yellow', 'pendown': False, 'fillcolor': '', 'stretchfactor': (1,1), 'speed': 3, 'shearfactor': 0.0} >>> p.pen(penstate, fillcolor="green") >>> p.pen() {'pensize': 10, 'shown': True, 'resizemode': 'auto', 'outline': 1, 'pencolor': 'red', 'pendown': True, 'fillcolor': 'green', 'stretchfactor': (1,1), 'speed': 3, 'shearfactor': 0.0} pencolor(*args) Return or set the pencolor. Arguments: Four input formats are allowed: - pencolor() Return the current pencolor as color specification string, possibly in hex-number format (see example). May be used as input to another color/pencolor/fillcolor call. - pencolor(colorstring) s is a Tk color specification string, such as "red" or "yellow" - pencolor((r, g, b)) *a tuple* of r, g, and b, which represent, an RGB color, and each of r, g, and b are in the range 0..colormode, where colormode is either 1.0 or 255 - pencolor(r, g, b) r, g, and b represent an RGB color, and each of r, g, and b are in the range 0..colormode If turtleshape is a polygon, the outline of that polygon is drawn with the newly set pencolor. Example: >>> pencolor('brown') >>> tup = (0.2, 0.8, 0.55) >>> pencolor(tup) >>> pencolor() '#33cc8c' pendown() Pull the pen down -- drawing when moving. Aliases: pendown | pd | down No argument. Example: >>> pendown() pensize(width=None) Set or return the line thickness. Aliases: pensize | width Argument: width -- positive number Set the line thickness to width or return it. If resizemode is set to "auto" and turtleshape is a polygon, that polygon is drawn with the same line thickness. If no argument is given, current pensize is returned. Example: >>> pensize() 1 pensize(10) # from here on lines of width 10 are drawn penup() Pull the pen up -- no drawing when moving. Aliases: penup | pu | up No argument Example: >>> penup() pos() Return the turtle's current location (x,y), as a Vec2D-vector. Aliases: pos | position No arguments.

No arguments. Example: >>> heading() 90 >>> radians() >>> heading() 1.5707963267948966 register_shape(name, shape=None) Adds a turtle shape to TurtleScreen's shapelist. Arguments: (1) name is the name of a gif-file and shape is None. Installs the corresponding image shape. !! Image-shapes DO NOT rotate when turning the turtle, !! so they do not display the heading of the turtle! (2) name is an arbitrary string and shape is a tuple of pairs of coordinates. Installs the corresponding polygon shape (3) name is an arbitrary string and shape is a (compound) Shape object. Installs the corresponding compound shape. To use a shape, you have to issue the command shape(shapename). call: register_shape("turtle.gif") --or: register_shape("tri", ((0,0), (10,10), (-10,10))) Example: >>> register_shape("triangle", ((5,-3),(0,5),(-5,-3))) reset() Delete the turtle's drawings and restore its default values. No argument. , Delete the turtle's drawings from the screen, re-center the turtle and set variables to the default values.

(Optional) Argument: rmode -- one of the strings "auto", "user", "noresize" Different resizemodes have the following effects: - "auto" adapts the appearance of the turtle corresponding to the value of pensize. - "user" adapts the appearance of the turtle according to the values of stretchfactor and outlinewidth (outline), which are set by shapesize() - "noresize" no adaption of the turtle's appearance takes place. If no argument is given, return current resizemode. resizemode("user") is called by a call of shapesize with arguments. Examples: >>> resizemode("noresize") >>> resizemode() 'noresize' right(angle) Turn turtle right by angle units. Aliases: right | rt Argument: angle -- a number (integer or float) Turn turtle right by angle units. (Units are by default degrees, but can be set via the degrees() and radians() functions.)

Aliases: setpos | setposition | goto: Arguments: x -- a number or a pair/vector of numbers y -- a number None call: goto(x, y) # two coordinates --or: goto((x, y)) # a pair (tuple) of coordinates --or: goto(vec) # e.g. as returned by pos() Move turtle to an absolute position. If the pen is down, a line will be drawn. The turtle's orientation does not change. Example: >>> tp = pos() >>> tp (0.00, 0.00) >>> setpos(60,30) >>> pos() (60.00,30.00) >>> setpos((20,80)) >>> pos() (20.00,80.00) >>> setpos(tp) >>> pos() (0.00,0.00) setposition(x, y=None) Move turtle to an absolute position.

Examples: >>> shape("circle") >>> shapesize(5,2) >>> settiltangle(45) >>> stamp() >>> fd(50) >>> settiltangle(-45) >>> stamp() >>> fd(50) setundobuffer(size) Set or disable undobuffer. Argument: size -- an integer or None If size is an integer an empty undobuffer of given size is installed. Size gives the maximum number of turtle-actions that can be undone by the undo() function. If size is None, no undobuffer is present. Example: >>> setundobuffer(42) setup(width=0.5, height=0.75, startx=None, starty=None) Set the size and position of the main window. Arguments: width: as integer a size in pixels, as float a fraction of the Default is 50% of height: as integer the height in pixels, as float a fraction of the Default is 75% of startx: if positive, starting position in pixels from the left edge of the screen, if negative from the right edge Default, startx=None is to center window horizontally. starty: if positive, starting position in pixels from the top edge of the screen, if negative from the bottom edge Default, starty=None is to center window vertically. Examples: >>> setup (width=200, height=200, startx=0, starty=0) sets window to 200x200 pixels, in upper left of screen >>> setup(width=.75, height=0.5, startx=None, starty=None) sets window to 75% of screen by 50% of screen and centers setworldcoordinates(llx, lly, urx, ury) Set up a user defined coordinate-system.

This performs a reset. If mode 'world' is already active, all drawings are redrawn according to the new coordinates. But ATTENTION: in user-defined coordinatesystems angles may appear distorted. (see Screen.mode()) Example: >>> setworldcoordinates(-10,-0.5,50,1.5) >>> for _ in range(36): left(10) forward(0.5) setx(x) Set the turtle's first coordinate to x Argument: x -- a number (integer or float) Set the turtle's first coordinate to x, leave second coordinate unchanged. Example: >>> position() (0.00, 240.00) >>> setx(10) >>> position() (10.00, 240.00) sety(y) Set the turtle's second coordinate to y Argument: y -- a number (integer or float) Set the turtle's first coordinate to x, second coordinate remains unchanged. Example: >>> position() (0.00, 40.00) >>> sety(-10) >>> position() (0.00, -10.00) shape(name=None) Set turtle shape to shape with given name / return current shapename. Optional argument: name -- a string, which is a valid shapename Set turtle shape to shape with given name or, if name is not given, return name of current shape. Shape with name must exist in the TurtleScreen's shape dictionary. Initially there are the following polygon shapes: 'arrow', 'turtle', 'circle', 'square', 'triangle', 'classic'. To learn about how to deal with shapes see Screen-method register_shape. Example: >>> shape() 'arrow' >>> shape("turtle") >>> shape() 'turtle' shapesize(stretch_wid=None, stretch_len=None, outline=None) Set/return turtle's stretchfactors/outline. Set resizemode to "user". Optinonal arguments: stretch_wid : positive number stretch_len : positive number outline : positive number Return or set the pen's attributes x/y-stretchfactors and/or outline. Set resizemode to "user". If and only if resizemode is set to "user", the turtle will be displayed stretched according to its stretchfactors: stretch_wid is stretchfactor perpendicular to orientation stretch_len is stretchfactor in direction of turtles orientation. outline determines the width of the shapes's outline. Examples: >>> resizemode("user") >>> shapesize(5, 5, 12) >>> shapesize(outline=8) shapetransform(t11=None, t12=None, t21=None, t22=None) Set or return the current transformation matrix of the turtle shape. Optional arguments: t11, t12, t21, t22 -- numbers. If none of the matrix elements are given, return the transformation matrix. Otherwise set the given elements and transform the turtleshape according to the matrix consisting of first row t11, t12 and second row t21, 22. Modify stretchfactor, shearfactor and tiltangle according to the given matrix. Examples: >>> shape("square") >>> shapesize(4,2) >>> shearfactor(-0.5) >>> shapetransform() >>> (4.0, -1.0, -0.0, 2.0) shearfactor(shear=None) Set or return the current shearfactor. Optional argument: shear -- number, tangent of the shear angle Shear the turtleshape according to the given shearfactor shear, which is the tangent of the shear angle. DO NOT change the turtle's heading (direction of movement). If shear is not given: return the current shearfactor, i. e. the tangent of the shear angle, by which lines parallel to the heading of the turtle are sheared. Examples: >>> shape("circle") >>> shapesize(5,2) >>> shearfactor(0.5) >>> shearfactor() >>> 0.5 showturtle() Makes the turtle visible. Aliases: showturtle | st No argument. Example: >>> hideturtle() >>> showturtle() speed(speed=None) Return or set the turtle's speed. Optional argument: speed -- an integer in the range 0..10 or a speedstring (see below) Set the turtle's speed to an integer value in the range 0 .. 10. If no argument is given: return current speed. If input is a number greater than 10 or smaller than 0.5, speed is set to 0. Speedstrings are mapped to speedvalues in the following way: 'fastest' : 0 'fast' : 10 'normal' : 6 'slow' : 3 'slowest' : 1 speeds from 1 to 10 enforce increasingly faster animation of line drawing and turtle turning. Attention: speed = 0 : *no* animation takes place. forward/back makes turtle jump and likewise left/right make the turtle turn instantly. Example: >>> speed(3) st() Makes the turtle visible. Aliases: showturtle | st No argument. Example: >>> hideturtle() >>> showturtle() stamp() Stamp a copy of the turtleshape onto the canvas and return its id. No argument. Stamp a copy of the turtle shape onto the canvas at the current turtle position. Return a stamp_id for that stamp, which can be used to delete it by calling clearstamp(stamp_id). Example: >>> color("blue") >>> stamp() 13 >>> fd(50) textinput(title, prompt) Pop up a dialog window for input of a string. Arguments: title is the title of the dialog window, prompt is a text mostly describing what information to input. Return the string input If the dialog is canceled, return None. Example: >>> textinput("NIM", "Name of first player:") tilt(angle) Rotate the turtleshape by angle. Argument: angle - a number Rotate the turtleshape by angle from its current tilt-angle, but do NOT change the turtle's heading (direction of movement). Examples: >>> shape("circle") >>> shapesize(5,2) >>> tilt(30) >>> fd(50) >>> tilt(30) >>> fd(50) tiltangle(angle=None) Set or return the current tilt-angle. Optional argument: angle -- number Rotate the turtleshape to point in the direction specified by angle, regardless of its current tilt-angle. DO NOT change the turtle's heading (direction of movement). If angle is not given: return the current tilt-angle, i. e. the angle between the orientation of the turtleshape and the heading of the turtle (its direction of movement). Deprecated since Python 3.1 Examples: >>> shape("circle") >>> shapesize(5,2) >>> tilt(45) >>> tiltangle() >>> title(titlestring) Set title of turtle-window Argument: titlestring -- a string, to appear in the titlebar of the turtle graphics window. This is a method of Screen-class. Not available for TurtleScreen- objects. Example: >>> title("Welcome to the turtle-zoo!") towards(x, y=None) Return the angle of the line from the turtle's position to (x, y). Arguments: x -- a number or a pair/vector of numbers or a turtle instance y -- a number None None call: distance(x, y) # two coordinates --or: distance((x, y)) # a pair (tuple) of coordinates --or: distance(vec) # e.g. as returned by pos() --or: distance(mypen) # where mypen is another turtle Return the angle, between the line from turtle-position to position specified by x, y and the turtle's start orientation. (Depends on modes - "standard" or "logo") Example: >>> pos() (10.00, 10.00) >>> towards(0,0) 225.0 tracer(n=None, delay=None) Turns turtle animation on/off and set delay for update drawings. Optional arguments: n -- nonnegative integer delay -- nonnegative integer If n is given, only each n-th regular screen update is really performed. (Can be used to accelerate the drawing of complex graphics.) Second arguments sets delay value (see RawTurtle.delay()) Example: >>> tracer(8, 25) >>> dist = 2 >>> for i in range(200): fd(dist) rt(90) dist += 2 turtles() Return the list of turtles on the Example: >>> turtles() [] turtlesize(stretch_wid=None, stretch_len=None, outline=None) Set/return turtle's stretchfactors/outline. Set resizemode to "user". Optinonal arguments: stretch_wid : positive number stretch_len : positive number outline : positive number Return or set the pen's attributes x/y-stretchfactors and/or outline. Set resizemode to "user". If and only if resizemode is set to "user", the turtle will be displayed stretched according to its stretchfactors: stretch_wid is stretchfactor perpendicular to orientation stretch_len is stretchfactor in direction of turtles orientation. outline determines the width of the shapes's outline. Examples: >>> resizemode("user") >>> shapesize(5, 5, 12) >>> shapesize(outline=8) undo() undo (repeatedly) the last turtle action. No argument. undo (repeatedly) the last turtle action. Number of available undo actions is determined by the size of the undobuffer. Example: >>> for i in range(4): fd(50); lt(80) >>> for i in range(8): undo() undobufferentries() Return count of entries in the undobuffer. No argument. Example: >>> while undobufferentries(): undo() up() Pull the pen up -- no drawing when moving. Aliases: penup | pu | up No argument Example: >>> penup() update() Perform a TurtleScreen update. width(width=None) Set or return the line thickness. Aliases: pensize | width Argument: width -- positive number Set the line thickness to width or return it. If resizemode is set to "auto" and turtleshape is a polygon, that polygon is drawn with the same line thickness. If no argument is given, current pensize is returned. Example: >>> pensize() 1 pensize(10) # from here on lines of width 10 are drawn window_height() Return the height of the turtle window. Example: >>> window_height() 480 window_width() Return the width of the turtle window. Example: >>> window_width() 640 write(arg, move=False, align='left', font=('Arial', 8, 'normal')) Write text at the current turtle position. Arguments: arg -- info, which is to be written to the TurtleScreen move (optional) -- True/False align (optional) -- one of the strings "left", "center" or right" font (optional) -- a triple (fontname, fontsize, fonttype) Write text - the string representation of arg - at the current turtle position according to align ("left", "center" or right") and with the given font. If move is True, the pen is moved to the bottom-right corner of the text. By default, move is False. Example: >>> write('Home = ', True, align="center") >>> write((0,0), True) write_docstringdict(filename='turtle_docstringdict') Create and write docstring-dictionary to file. Optional argument: filename -- a string, used as filename default value is turtle_docstringdict Has to be called explicitely, (not used by the turtle-graphics classes) The docstring dictionary will be written to the Python script .py It is intended to serve as a template for translation of the docstrings into different languages. xcor() Return the turtle's x coordinate. No arguments. Example: >>> reset() >>> left(60) >>> forward(100) >>> print xcor() 50.0 ycor() Return the turtle's y coordinate --- No arguments. Example: >>> reset() >>> left(60) >>> forward(100) >>> print ycor() 86.6025403784 DATA __all__ = ['ScrolledCanvas', 'TurtleScreen', 'Screen', 'RawTurtle', 'T... >>> my_screen = turtle.Screen() >>> my_turtle = turtle.Turtle() >>> my_turtle.pd() >>> my_turtle.fd(100) >>> my_turtle.left(90) >>> my_turtle.fd(100) >>> for iteration in range(2): my_turtle.left(90) my_turtle.forward(100) >>> my_turtle.pu() >>> my_turtle.fd(200) >>> my_turtle.left(90) >>> for iteration in range(4): my_turtle.fd(100) my_turtle.left(90) >>> my_turtle.pd() >>> for iteration in range(4): my_turtle.fd(100) my_turtle.left(90) >>> howie = turtle.Turtle() >>> howie.right(180) >>> howie.pu() >>> howie.forward(50) >>> howie.pd() >>> howie.fd(100) >>> import math >>> help(math) Help on module math: NAME math FILE /Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/lib-dynload/math.so MODULE DOCS http://docs.python.org/library/math DESCRIPTION This module is always available.
