Python Snowflake (Computer Science Christmas Competition)
Below is some code that uses a turtle to draw a snowflake. See if you can edit the code to make a unique snowflake of your own.
Hint: the #screen.bgpic("my_image.jpg") line can be used to add a background picture.
import turtle
from turtle import *
def snowflake(l, d):
screen = turtle.Screen()
#screen.bgpic("my_image.jpg")
screen.bgcolor("black")
if d > 0:
for i in range(6):
speed("fastest")
color("silver")
width(5)
forward(l)
snowflake(l // 3, d - 1)
backward(l)
left(60)
snowflake(200,4)
Other codes to try.....
import turtle
import random
# setup the window with a background colour
wn = turtle.Screen()
wn.bgcolor("#EFECCA")
wn.setup(width=250, height=250)
# assign a name to your turtle
turtle = turtle.Turtle()
colors = ["#7D8A2E", "#263248", "#FF8C00", "#F0C600"]
#
def snowflake(size, pensize, x, y):
""" function that draws a snowflake """
# turtle.pen(pensize=10)
turtle.penup()
turtle.goto(x, y)
turtle.forward(10*size)
turtle.left(45)
turtle.pendown()
turtle.color(random.choice(colors))
for i in range(8):
branch(size)
turtle.left(45)
# create one branch of the snowflake
def branch(size):
for i in range(3):
for i in range(3):
turtle.forward(10.0*size/3)
turtle.backward(10.0*size/3)
turtle.right(45)
turtle.left(90)
turtle.backward(10.0*size/3)
turtle.left(45)
turtle.right(90)
turtle.forward(10.0*size)
snowflake(8, 6, 0, 0)
# leave the window open until you click to close
wn.exitonclick()
And another....
import turtle
from turtle import *
def snowflake(l, d):
screen = turtle.Screen()
#screen.bgpic("my_image.jpg")
screen.bgcolor("black")
if d > 0:
for i in range(6):
speed("fastest")
color("silver")
width(5)
forward(l)
snowflake(l // 3, d - 1)
backward(l)
left(60)
snowflake(200,4)
