5.7. Practice - Write a Procedure

Time for a little practice - try writing your own procedure. There is an answer available, but don’t look at it until you have tried writing the procedure on your own!

Turtle procedures

The main part of this program is written. It makes a turtle emily and then tries to call the pentagon function to use emily to draw a pentagon (5 sided figure) of size 100. However, the pentagon function has not been defined. You need to write it to complete the program.

Hint: To figure out the angle to turn while drawing a regular shape, you need to divide 360 by the number of sides. \(360 / 5 = 72\).

# DEFINE THE PROCEDURE HERE # Main part of program from turtle import * space = Screen() emily = Turtle() # CALL THE PROCEDURE pentagon(emily, 100)

# DEFINE THE PROCEDURE def pentagon(turtle, size): turtle.forward(size) turtle.right(72) turtle.forward(size) turtle.right(72) turtle.forward(size) turtle.right(72) turtle.forward(size) turtle.right(72) turtle.forward(size) turtle.right(72) # Main part of program from turtle import * space = Screen() emily = Turtle() # CALL THE PROCEDURE pentagon(emily, 100)
