python跨年代码动态

### Python 编写跨年动态效果代码示例

#### 使用 Pygame 实现跨年烟花秀

为了实现一个生动的跨年烟花秀，可以利用 `pygame` 库的强大功能。下面是一个完整的代码实例，该程序不仅实现了基本的烟花发射和爆炸效果，还加入了色彩渐变以及随机生成的不同形状的烟花。

import pygame
import random
from math import sin, cos, radians

# 初始化 Pygame 和屏幕设置
pygame.init()
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption('Happy New Year Fireworks Show')

class Particle(pygame.sprite.Sprite):
    def __init__(self, x, y, color, size=10):
        super().__init__()
        self.image = pygame.Surface([size * 2, size * 2])
        self.rect = self.image.get_rect(center=(x, y))
        self.color = color
        self.size = size
        self.x_speed = (random.random() - 0.5) * 10
        self.y_speed = -(random.random() + 0.5) * 10
    
    def update(self):
        self.rect.x += int(self.x_speed)
        self.rect.y += int(self.y_speed)
        self.size -= 0.1
        if self.size <= 0:
            self.kill()

def create_firework(x, y):
    colors = [(255, 0, 0), (0, 255, 0), (0, 0, 255)]
    particles_group.empty()
    for _ in range(100):  
        particle_color = random.choice(colors)
        new_particle = Particle(x, y, particle_color)
        all_sprites.add(new_particle)

all_sprites = pygame.sprite.Group()
particles_group = pygame.sprite.Group()

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        
        elif event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
            mouse_x, mouse_y = pygame.mouse.get_pos()
            create_firework(mouse_x, mouse_y)

    screen.fill((0, 0, 0))  # 清屏并填充黑色作为夜空背景
            
    all_sprites.update()
    
    for sprite in all_sprites.sprites():
        pygame.draw.circle(screen, sprite.color, sprite.rect.center, int(sprite.size))

    pygame.display.flip()
    pygame.time.Clock().tick(30)

pygame.quit()

这段代码通过鼠标点击触发烟花的生成，在屏幕上呈现出绚丽多彩的新年烟火表演[^4]。
