TurtleWorld Exercises
1. Write a function called square that takes a parameter named t, which is a turtle. It should use the turtle to draw a square.
- from TurtleWorld import *
- def square(t):
- for i in range(4):
- fd(t,100)
- lt(t)
- TurtleWorld()
- bob = Turtle()
- square(bob)
2. Add a parameter , named length, to square. Modify the body so length of the sides is length, and then modify the function call to provide a second argument.
- from TurtleWorld import *
- def square(t,length):
- for i in range(4):
- fd(t,length)
- lt(t)
- TurtleWorld()
- bob = Turtle()
- square(bob,50)
3. Provide an argument to that specify the numbers of degrees. For example lt(bob,45) turns bob 45 degrees to the left.
- from TurtleWorld import *
- def polygon(t,length,degree):
- n = int(360/degree)
- for i in range(n):
- fd(t,length)
- lt(t,degree)
- TurtleWorld()
- bob = Turtle()
- polygon(bob,100,60)
4. Write a function called circle that draws an approximative circle.
- from TurtleWorld import *
- import math
- def circle(t,r):
- for i in range(360):
- fd(t,int((2*math.pi*r)/360))
- lt(t,1)
- TurtleWorld()
- bob = Turtle()
- bob.delay = 0.01 # speed up bob to draw the circle
- circle(bob,100)
