python烟花跨年

以下是一个使用turtle库在Python中实现烟花跨年的例子：

import turtle
import random

# 创建烟花
def create_firework():
    fireworks = []
    shapes = ['circle', 'classic', 'square', 'triangle', 'arrow', 'turtle']
    
    for i in range(25):
        new_firework = turtle.Turtle()
        new_firework.speed('fastest')
        new_firework.up()
        new_firework.ht()
        new_firework.shape(random.choice(shapes))
        new_firework.shapesize(0.5, 2.5)
        fireworks.append(new_firework)
    
    return fireworks

# 爆炸效果
def explode(fireworks):
    for firework in fireworks:
        firework.goto(random.randint(-200, 200), random.randint(-200, 200))
        firework.showturtle()

# 主函数
def main():
    turtle.setup(800, 600)
    turtle.bgcolor('black')
    turtle.title('2022烟花跨年')
    
    fireworks = create_firework()
    
    while True:
        explode(fireworks)
        turtle.update()
        turtle.clear()
    
    turtle.done()

# 运行主函数
if __name__ == '__main__':
    main()

这段代码使用turtle库创建了25个烟花，每个烟花的形状随机选择。然后，烟花会在屏幕上随机位置爆炸，形成跨年的烟花效果。
