用Python写一个谢尔宾斯基三角，用递归写五层

好的，我可以回答这个问题。以下是用 Python 递归实现五层谢尔宾斯基三角的代码：

import turtle

def draw_triangle(points, color, my_turtle):
    my_turtle.fillcolor(color)
    my_turtle.up()
    my_turtle.goto(points[0][0], points[0][1])
    my_turtle.down()
    my_turtle.begin_fill()
    my_turtle.goto(points[1][0], points[1][1])
    my_turtle.goto(points[2][0], points[2][1])
    my_turtle.goto(points[0][0], points[0][1])
    my_turtle.end_fill()

def get_mid(p1, p2):
    return ((p1[0]+p2[0])/2, (p1[1]+p2[1])/2)

def sierpinski(points, degree, my_turtle):
    colormap = ['blue','red','green','white','yellow','violet','orange']
    draw_triangle(points, colormap[degree], my_turtle)
    if degree > 0:
        sierpinski([points[0],
                    get_mid(points[0], points[1]),
                    get_mid(points[0], points[2])],
                   degree-1, my_turtle)
        sierpinski([points[1],
                    get_mid(points[0], points[1]),
                    get_mid(points[1], points[2])],
                   degree-1, my_turtle)
        sierpinski([points[2],
                    get_mid(points[2], points[1]),
                    get_mid(points[0], points[2])],
                   degree-1, my_turtle)

def main():
    my_turtle = turtle.Turtle()
    my_win = turtle.Screen()
    my_points = [[-200,-100],[0,200],[200,-100]]
    sierpinski(my_points, 5, my_turtle)
    my_win.exitonclick()

main()

希望这个代码能够帮到你！
