python生日快乐烟花代码

以下是Python实现生日快乐烟花的代码：

import turtle
import random

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

# 定义烟花函数
def firework():
    # 设置画笔颜色和大小
    turtle.pencolor(random.choice(['red', 'yellow', 'blue', 'white', 'green', 'purple', 'orange']))
    turtle.pensize(3)
    # 随机生成烟花起点和终点坐标
    x = random.randint(-350, 350)
    y = random.randint(-250, 250)
    end_x = random.randint(-50, 50)
    end_y = random.randint(200, 400)
    # 移动画笔到起点
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    # 绘制烟花
    turtle.speed(0)
    turtle.goto(end_x, end_y)
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.goto(end_x, end_y)

# 循环绘制烟花
while True:
    firework()

# 点击关闭窗口
turtle.exitonclick()
