帮我写一个生成烟花的python代码

以下是一个简单的生成烟花效果的Python代码，使用了Pygame库：

import pygame
import random

# 初始化Pygame
pygame.init()

# 设置屏幕大小
screen = pygame.display.set_mode((800, 600))

# 设置颜色
WHITE = (255, 255, 255)
YELLOW = (255, 255, 0)
RED = (255, 0, 0)
ORANGE = (255, 128, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
PURPLE = (128, 0, 128)

# 定义烟花类
class Firework:
    def __init__(self, x, y, color):
        self.x = x
        self.y = y
        self.color = color
        self.exploded = False
        self.particles = []

    def explode(self):
        for i in range(100):
            speed = random.randint(1, 10)
            angle = random.uniform(0, 2 * 3.14159)
            dx = speed * math.sin(angle)
            dy = speed * math.cos(angle)
            particle = Particle(self.x, self.y, self.color, dx, dy)
            self.particles.append(particle)
        self.exploded = True

    def draw(self):
        if not self.exploded:
            pygame.draw.circle(screen, self.color, (self.x, self.y), 5)
        else:
            for particle in self.particles:
                particle.draw()

# 定义粒子类
class Particle:
    def __init__(self, x, y, color, dx, dy):
        self.x = x
        self.y = y
        self.color = color
        self.dx = dx
        self.dy = dy
        self.lifetime = random.randint(10, 50)

    def move(self):
        self.x += self.dx
        self.y += self.dy
        self.lifetime -= 1

    def draw(self):
        pygame.draw.circle(screen, self.color, (int(self.x), int(self.y)), 3)

    def is_dead(self):
        return self.lifetime <= 0

# 创建烟花列表
fireworks = []

# 游戏循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEBUTTONDOWN:
            # 在鼠标位置生成烟花
            x, y = event.pos
            color = random.choice([YELLOW, RED, ORANGE, GREEN, BLUE, PURPLE])
            firework = Firework(x, y, color)
            fireworks.append(firework)

    # 更新烟花和粒子
    for firework in fireworks:
        if not firework.exploded:
            firework.draw()
            if random.random() < 0.01:
                firework.explode()
        else:
            for particle in firework.particles:
                particle.move()
                particle.draw()
            firework.particles = [p for p in firework.particles if not p.is_dead()]

    # 更新屏幕
    pygame.display.flip()

# 退出Pygame
pygame.quit()
