18. Turtle Graphics: Hypnotic Pattern

use a loop with the turtle graphics library to draw the design shown in Figure 4-15

Answer 1

import turtle

# import turtle

win = turtle.Screen()

win.screensize(400 * 400)

# create window screen with 400 * 400 width and height

tur = turtle.Turtle()

n = 4

# initialize n= 4

for i in range(2 * n):

    # find the value of angle and make turtle to rotate by that angle

    angle = 180 - 180 / n

    tur.forward(200)

    tur.right(angle)

turtle.done()

import turtle # import turtle win = turtle.Screen() win.screensize(400 * 400) # create window screen with 400 * 400 width and height tur = turtle. Turtle() n = 4 # initialize n= 4 Fifor i in range(2 * n): # find the value of angle and make turtle to rotate by that angle angle = 180 - 180 / n tur.forward(200) tur.right(angle) turtle.done (1)

Python Turtle Graphics

# import turtle
import turtle
# create screen of 400 * 400 width and height
win =turtle.Screen()
win.screensize(400 * 400)
# create turtle object
tur = turtle.Turtle()
# move turtle to its left by 90 degrees
tur.left(90)
# this for loop runs till 150 with the step count by 4
for i in range(0, 150, 4):
    # move turtle to forward direction for a distance of i+4 and make it rotate by 90 degree to its left
    tur.forward(i+5)
    tur.left(90)
turtle.done()

# import turtle import turtle # create screen of 400 * 400 width and height win =turtle.Screen() win.screensize(400 * 400) # create turtle object tur = turtle.
