python画烟花

以下是用Python实现画烟花的代码：

import turtle
import random

# 设置画布大小和背景颜色
turtle.setup(800, 600)
turtle.bgcolor("black")

# 定义画烟花的函数
def draw_firework():
    # 设置画笔颜色和粗细
    turtle.pencolor(random.choice(["red", "orange", "yellow", "green", "blue", "purple", "white"]))
    turtle.pensize(3)

    # 画出烟花的花朵部分
    for i in range(30):
        turtle.forward(15)
        turtle.left(12)

    # 画出烟花的爆炸部分
    turtle.pensize(6)
    for i in range(15):
        turtle.backward(30)
        turtle.right(24)
        turtle.pencolor(random.choice(["red", "orange", "yellow", "green", "blue", "purple", "white"]))
        turtle.pensize(random.randint(2, 5))
        turtle.forward(30)

# 循环画烟花
while True:
    # 隐藏画笔
    turtle.hideturtle()

    # 设置画笔起点和方向
    turtle.up()
    turtle.goto(random.randint(-400, 400), random.randint(-300, 300))
    turtle.down()
    turtle.setheading(random.randint(0, 360))

    # 画出一朵烟花
    draw_firework()

# 点击关闭窗口
turtle.exitonclick()

运行代码后，会在窗口中随机画出多朵烟花。每朵烟花的花朵部分由30条线段组成，爆炸部分由15条线段组成，颜色和粗细随机生成。
