The Koch Curve as Snowflake with Python Turtle Graphics

Posted on by Markus

It’s over midnight here.. Since the source code in one of my videos is not very readable, I decided to publish the Python source code of the video in this blog post.

import turtle


def draw_curve():  
   window = turtle.Screen()  
   turt=turtle.Turtle()
   turt.setpos(-300,-100)
   turt.clear()
   turt.speed('fastest')
   turt.hideturtle()
    
   vonKoch(turt,5,500)
   turt.left(120)
   vonKoch(turt,5,500)
   turt.left(120)
   vonKoch(turt,5,500)
   turt.left(120)
   vonKoch(turt,5,500)
   window.exitonclick()  

def vonKoch(turt,depth,length):
    if depth == 0: turt.forward(length)
    else:
        vonKoch(turt,depth-1,length/3)
        turt.right(60)
        vonKoch(turt,depth-1,length/3)
        turt.left(120)
        vonKoch(turt,depth-1,length/3)
        turt.right(60)
        vonKoch(turt,depth-1,length/3)
        



draw_curve()

That’s it for now. Time to go to sleep.
