A turtle can be commanded to crawl over a sheet of paper with a pen tied to its tail. The turtle module in Python allows you to control a turtle shape to draw on a graphic window. Basic turtle commands include moving the turtle forward or turning it right by a set number of degrees. Challenges for using the turtle include drawing shapes like squares and hexagons of varying sides, as well as getting the turtle to draw a person's initials.

Turtle module
Sets up a Turtle and makes
it a Turtle Shape
Moves forward 100 pixels
Turns right by 90 degrees
Closes the graphic window
when you quit

4. Challenges

Draw a square:
 By repeating the same commands four times

 Using ‘For I in range(4):’ 


Draw a hexagon
Allow the user to say how many sides
the polygon should have
 Remember, use
‘myVariable = int(raw_input)’ to get a
