Explanation:

Function drawCircle

-Expect Turtle object, coordinates of the circle's center point and

circle's radius as arguments

-Function draws circle

-Draw circle's circumference by turning 3 degrees and moving a given

distance, 120 times.

-Calculate the distance moved with formula 2.0 * 3.14 * radius /120

"""

def drawCircle (turtle, centerpoint, radius):

circumference = 2 * 3.14 * (radius/120)

print "The circumference moved is", circumference

turtle.up()

(x,y) = centerpoint[-1]

turtle.turn(3)

turtle.move(120)

turtle.down()

from turtlegraphics import Turtle

turtle=Turtle()

drawCircle(turtle, [(20,20)], 20)
