Looping Examples-Graphics with the Turtle Library
# Example #1:
# import the turtle method
import turtle
# get the Screen
window = turtle.Screen
# initialize Turtle Variable
bob = turtle.Turtle()
# Make speed fast (0 is the fastest)
bob.speed(0)
# for loop
# start = 0, stop = 250, iteration = 1 (you don't have to put this because if no iteration is typed in the range, it assumes the iteration is 1.
for i in range(0,250):
# move bob forward and iterate by 1 to make bob loop
bob.forward(i+1)
# we are trying to make the base hexogonal and iterate it
# we use bob.left(60) to turn bob 60 degrees (the angle of each
side of a hexagon)
bob.left(60)
Output:
# Example #2:
# import Turtle Method
import turtle
# get Screen
window = turtle.Screen
# Initialize Turtle (I named mine 'bob')
bob = turtle.Turtle()
# make speed fast (zero = fastest)
bob.speed(0)
# for-loop
# start = 0, end = 500, iteration = 1
for i in range(0,500):
# move bob forward and iterate by 1
bob.forward(i+1)
# move bob left by 65 degrees (always go a couple of degrees off from the angle of a side of a hexagon if you want to create the hexagonal spiral like shape
bob.left(65)
