Random Turtle Shapes (Python)

After yesterday’s Code Club, my son asked if it would be possible to use Turtle to draw shapes randomly. I explained that it should be simple to define some shapes and then have use Python to randomly draw them in at random areas on the screen, which quickly lead to a program being knocked up…

#!/bin/python3

#random turtle

#libraries to import
from random import *

#defining shapes
def square():
for x in range(4):
forward(50)
right(90)

def triangle():
for side in range(3):
forward(50)
right(120)

#set up the area for turtle to use
area = Screen()
area.setup(500,500)
area.bgcolor(‘white’)

#num in range defines how many shapes to create
for num in range(200):
hideturtle()
#speed shapes are drawn
turtle_speed=randint(0,9)
speed(turtle_speed)
#creates a random number between 1 and 4
random_shape=randint(1,4)
#creates a random number between 1 and 4
pen_color=randint(1,4)
#creates a random number between -200 and 200
rand_x=randint(-200,200)
#creates a random number between -200 and 200
rand_y=randint(-200,200)

#goes through pen colour options
if pen_color==1:
pencolor(‘black’)
elif pen_color==2:
pencolor(‘blue’)
elif pen_color==3:
pencolor(‘red’)
elif pen_color==4:
pencolor(‘green’)

#goes through shapes options
if random_shape==1:
penup()
goto(rand_x,rand_y)
pendown()
circle(50)
elif random_shape==2:
penup()
goto(rand_x,rand_y)
pendown()
square()
elif random_shape==3:
penup()
goto(rand_x,rand_y)
pendown()
dot(10)

goto(rand_x,rand_y)
pendown()
