用科赫曲线Python画一个小房子

好的，下面是代码：

import turtle

def koch_curve(t, order, size):
    if order == 0:
        t.forward(size)
    else:
        for angle in [60, -120, 60, 0]:
            koch_curve(t, order-1, size/3)
            t.left(angle)

def draw_house():
    # 初始化画布
    window = turtle.Screen()
    window.bgcolor("white")

    # 初始化画笔
    pen = turtle.Turtle()
    pen.speed(0)
    pen.color("black")
    pen.penup()
    pen.goto(-200, -150)
    pen.pendown()
    pen.pensize(2)

    # 画正方形
    for i in range(4):
        pen.forward(200)
        pen.left(90)

    # 画屋顶
    pen.left(45)
    koch_curve(pen, 3, 200)
    pen.right(90)
    koch_curve(pen, 3, 200)
    pen.right(45)

    # 画门
    pen.penup()
    pen.goto(-50, -150)
    pen.pendown()
    pen.right(90)
    pen.forward(100)
    pen.left(90)
    pen.forward(60)
    pen.left(90)
    pen.forward(40)
    pen.left(90)
    pen.forward(60)

    # 画窗户
    pen.penup()
    pen.goto(-150, -50)
    pen.pendown()
    pen.right(90)
    pen.forward(60)
    pen.left(90)
    pen.forward(60)
    pen.left(90)
    pen.forward(60)
    pen.left(90)
    pen.forward(60)
    
    # 隐藏画笔
    pen.hideturtle()

    # 等待关闭窗口
    turtle.done()

# 调用函数
draw_house()

运行代码，会弹出一个窗口，显示一个小房子，如下图所示：
