python过年烟花代码免费

### Python代码实现烟花效果 为了创建模拟烟花的效果，可以利用`pygame`库来处理图形和动画。下面是一个简单的例子，展示了如何使用Python编写一个基本的烟花爆炸效果程序[^1]。 ```python import pygame import random import math # 初始化Pygame模块 pygame.init() # 设置屏幕大小 screen_width, screen_height = 800, 600 screen = pygame.display.set_mode((screen_width, screen_height)) class Particle(pygame.sprite.Sprite): """定义粒子类""" def __init__(self, x, y, color=(255, 255, 255)): super().__init__() self.image = pygame.Surface([4, 4]) self.rect = self.image.get_rect() self.color = color # 给定随机方向和速度 angle = random.uniform(0, 2 * math.pi) speed = random.uniform(2, 7) self.change_x = math.sin(angle) * speed self.change_y = math.cos(angle) * (-speed) self.x = x self.y = y def update(self): """更新位置并应用重力""" self.x += self.change_x self.y += self.change_y self.change_y += 0.1 # 加入重力效应 self.rect.x = int(self.x) self.rect.y = int(self.y) def create_firework(x, y): """创造一组新的烟火颗粒""" colors = [(255, 0, 0), (0, 255, 0), (0, 0, 255)] particles_group = pygame.sprite.Group() for _ in range(random.randint(50, 100)): particle_color = random.choice(colors) new_particle = Particle(x, y, particle_color) particles_group.add(new_particle) return particles_group done = False clock = pygame.time.Clock() while not done: for event in pygame.event.get(): if event.type == pygame.QUIT or \ (event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE): done = True elif event.type == pygame.MOUSEBUTTONDOWN: mouse_pos = pygame.mouse.get_pos() firework_particles = create_firework(mouse_pos[0], mouse_pos[1]) screen.fill((0, 0, 0)) try: firework_particles.update() firework_particles.draw(screen) except AttributeError: pass pygame.display.flip() clock.tick(60) pygame.quit() ``` 这段代码通过鼠标点击触发，在屏幕上生成彩色的小圆点代表火花，并让这些点按照抛物线轨迹运动，模仿真实的烟花绽放过程[^1]。
