用python随机颜色画风车

以下是一个随机颜色画风车的python程序：

import turtle
import random

# 设置画布和画笔
canvas = turtle.Screen()
canvas.bgcolor("white")
pen = turtle.Turtle()
pen.speed(0)
pen.pensize(3)

# 定义颜色列表
colors = ["red", "orange", "yellow", "green", "blue", "purple"]

# 循环画风车
for i in range(4):
    # 随机选择颜色
    color = random.choice(colors)
    pen.color(color)

    # 画风车的四个部分
    pen.forward(100)
    pen.right(90)
    pen.forward(100)
    pen.right(135)
    pen.forward(140)
    pen.right(135)
    pen.forward(100)
    pen.right(90)

# 隐藏画笔
pen.hideturtle()

# 点击关闭窗口
canvas.exitonclick()

运行上述代码，可以生成一个随机颜色的风车。每次运行程序，其颜色都会不同。
