ASSIGNMENT 6

Due: Monday, August 5th

Any characters not supported by display should simply be skipped on output.

Your program should print out the letters horizontally, and go to a new "line" when you input a space. Thus, each 'word' will be on a different line. Also, make certain you leave some space between each letter.

Your program should be completely structured and use at least three levels of functions - as described below.

First, here is an example of the fourteen segments all displayed at once. (Note that your version does NOT have to have points at the end of the segments: They can simply be straight lines.)

You should produce functions for each letter, for each number and for the 'space' character. For example, the function for A would not directly call its seven segments directly, but would be composed of perhaps four further calls:

def MethodA (width) : top_stroke(width) middle_stroke(width) left_stroke right_stroke(width)

Note that the *width* of a character needs to be sent to any function which is dependent upon it.  If you define the lower-left
corner as the "home position" for the turtle, it does *not* need to know the width of the letter to draw the left_stroke, but
it *does* need to know the width to draw the right_stroke in order to position properly. 

The code for right_stroke might look like:

def right_stroke(width): top_right(width) bottom_right(width)

Finally, bottom_right would actually call the turtle graphics routines and at long last draw a single line.

def bottom_right(width): *some turtle graphic functions*

On the other hand, the letter "H" would be produced by the following sequence:

Def MethodH( width) : right_stroke(width) left_stroke middle_stroke (width)

Hint:  Always make your turtle go back to the same point (say, the lower-left) after drawing each stroke.  
That way, the order of the strokes will not matter!

So, if your data file contains: 

108     (the width of the character!)
PYTHON IS FUN    

The output should look like:

PART TWO:

• When you are done and have tested it, zip your source code and your data files together, and post post them as something like "smith_john_assign6.zip" to "NYU Classes".

 Notes about your program:

• Make sure your program includes a comment at the beginning of the program, listing your personal
  info along with a brief synopsis of the program's function.
• You should use comments throughout the source code to explain key steps and calculations.
• Choose intuitive names for variables.
