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)
