Home Work Assignment Number 4

1. Read Chapter 5 in Donaldson book (we will read chapter 4 after we finish 5)
   
2. Write a program:
1. Use the turtle library to draw a picture.
2. Look at the Manual for Python's turtle graphics to help you figure out how to use additional portions of Turtle Graphics that we did not cover in class: http://docs.python.org/py3k/library/turtle.html
3. You can also look at the 4 square programs I used in class to help you: four_squares.py and four_squares2.py
4. Include at least a stick figure in your picture.  A google image search illustrates what a stick figure is, in case you are unfamiliar with the term (or want some inspiration).
5. If you want the figure to have a round head use my_turtle.circle(NUMBER) where NUMBER is the radius of the circule (e.g., 50)
6. Include functions that encapsulate code for reuse.
• Examples: draw_left_arm, draw_left_leg, draw_stick_figure
  
• These functions could make it easier for your code to be understood, to draw multiple stick figures, etc.
  
3. Criteria for grading:
1. Does your code draw at least one stick figure?
2. Do you have functions that encapsulate ideas, e.g., draw_left_arm, draw_right_arm, etc.?
3. Is your code easy to run?  For example, it would be good to either:
• Have a main function that runs your code. You can call this main function at the end of your .py file.
• Or you could have really good instructions (in comments) explaining how to run the code.
4. Do you do anything interesting or creative?
• Did you find out anything interesting when you looked up the turtle document that you tried when you ran the code?
