python生日快乐烟花动画代码

在Python中制作生日快乐烟花动画，可以使用`pygame`库来创建图形和控制动画。下面是一个简单的示例代码，它会在屏幕上绘制出烟花效果，并循环播放“Happy Birthday”祝福语：

import pygame
import random

# 初始化Pygame
pygame.init()

# 设置窗口大小
screen = pygame.display.set_mode((640, 480))
pygame.display.set_caption("Happy Birthday Fireworks")

# 定义颜色
colors = [(255, 0, 0), (0, 255, 0), (0, 0, 255)]
firework_colors = [random.choice(colors) for _ in range(20)]

# 烟花位置和速度
fireworks = []
for i in range(10):
    fireworks.append((random.randint(0, screen.get_width()), random.randint(0, screen.get_height()), 0, 10))

font = pygame.font.SysFont(None, 36)

# 游戏主循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()

    # 清除屏幕
    screen.fill((0, 0, 0))

    # 绘制烟花
    for firework in fireworks:
        x, y, speed, size = firework
        size += speed
        pygame.draw.circle(screen, firework_colors.pop(), (x, y), size)
        
        # 当烟花达到一定大小时消失并随机生成新的烟花
        if size > 100:
            fireworks.remove(firework)
            new_firework = (random.randint(0, screen.get_width()), random.randint(0, screen.get_height()), -speed / 2, 10)
            fireworks.append(new_firework)

    # 显示文字祝福
    text = font.render('Happy Birthday', True, (255, 255, 255))
    screen.blit(text, (0, 0))

    # 更新屏幕
    pygame.display.flip()
