Draw Snowflakes in Python Using Turtle

Python Program to Draw Snowflakes Using Turtle

#Draw Snowflakes in Python Using Turtle

import turtle
import random

# setup the window with a background colour
wn = turtle.Screen()
wn.bgcolor("black")

# assign a name to your turtle
elsa = turtle.Turtle()
elsa.speed(0)

# create a list of colours
sfcolor = ["white", "blue", "red", "grey", "magenta"]

# create a function to create different size snowflakes
def snowflake(size):
# move the pen into starting position
	elsa.penup()
	elsa.forward(10*size)
	elsa.left(45)
	elsa.pendown()
	elsa.color(random.choice(sfcolor))
	# draw branch 8 times to make a snowflake
	for i in range(8):
    	branch(size)   
    	elsa.left(45)
    

# create one branch of the snowflake
def branch(size):
	for i in range(3):
    	for i in range(3):
        	elsa.forward(10.0*size/3)
        	elsa.backward(10.0*size/3)
        	elsa.right(45)
    	elsa.left(90)
    	elsa.backward(10.0*size/3)
    	elsa.left(45)
	elsa.right(90)
	elsa.forward(10.0*size)

# loop to create 20 different sized snowflakes with different starting co-ordinates
for i in range(20):
	x = random.randint(-200, 200)
	y = random.randint(-200, 200)
	sf_size = random.randint(1, 4)
	elsa.penup()
	elsa.goto(x, y)
	elsa.pendown()
	snowflake(sf_size)

# leave the window open until you click to close  
wn.exitonclick()
