科赫雪花python代码6阶

以下是利用Python实现科赫雪花的代码，可以绘制6阶的科赫雪花图案：

import turtle

def koch(size, n):
    if n == 0:
        turtle.fd(size)
    else:
        for angle in [0, 60, -120, 60]:
            turtle.left(angle)
            koch(size/3, n-1)

def main():
    turtle.setup(800,400)
    turtle.penup()
    turtle.goto(-300, -50)
    turtle.pendown()
    turtle.pensize(2)
    level = 6
    koch(600, level)
    turtle.right(120)
    koch(600, level)
    turtle.right(120)
    koch(600, level)
    turtle.hideturtle()
    turtle.done()

main()
