python海龟绘图 清明节

好的，我知道了。关于python海龟绘图清明节，可以画出一棵柳树和一些飞舞的柳絮，代码如下：

import turtle

# 画柳树
def draw_tree():
    turtle.color('green')
    turtle.pensize(5)
    turtle.penup()
    turtle.goto(-200, -200)
    turtle.pendown()
    turtle.left(90)
    turtle.forward(100)
    draw_branch(80, 60, 0.6)
    turtle.penup()
    turtle.goto(-200, -200)
    turtle.pendown()
    draw_branch(80, 60, 0.6)

# 画树枝
def draw_branch(branch_length, angle, scale):
    if branch_length > 5:
        turtle.pensize(scale * 10)
        turtle.forward(branch_length)
        turtle.right(angle)
        draw_branch(branch_length * scale, angle * 0.8, scale * 0.9)
        turtle.left(angle * 2)
        draw_branch(branch_length * scale, angle * 0.8, scale * 0.9)
        turtle.right(angle)
        turtle.backward(branch_length)

# 画柳絮
def draw_flower():
    turtle.color('white')
    turtle.penup()
    turtle.goto(-200, 200)
    turtle.pendown()
    turtle.begin_fill()
    turtle.circle(20)
    turtle.end_fill()

# 主函数
def main():
    turtle.speed(0)
    draw_tree()
    for i in range(10):
        draw_flower()
        turtle.right(36)
    turtle.hideturtle()
    turtle.done()

if __name__ == '__main__':
    main()
