python春节动态代码

以下是一个使用Python编写的春节动态代码的示例，其中包括了背景图、背景音乐和烟花效果等元素。你可以根据自己的需要进行修改和定制。

import pygame
import random

# 初始化pygame
pygame.init()

# 设置屏幕大小和标题
screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("Happy Spring Festival")

# 加载背景图和音乐
background = pygame.image.load("background.jpg")
pygame.mixer.music.load("music.mp3")
pygame.mixer.music.play(-1)

# 定义烟花粒子类
class Particle:
    def __init__(self, x, y, size, color):
        self.x = x
        self.y = y
        self.size = size
        self.color = color
        self.speed = random.randint(1, 5)
        self.angle = random.uniform(0, 2 * math.pi)

    def move(self):
        self.x += self.speed * math.cos(self.angle)
        self.y += self.speed * math.sin(self.angle)
        self.size -= 0.1
        self.color = (self.color[0], self.color[1], self.color[2], int(self.color[3] * 0.9))

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

# 定义烟花效果类
class Firework:
    def __init__(self, x, y):
        self.particles = []
        self.color = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255), 255)
        for i in range(100):
            self.particles.append(Particle(x, y, 5, self.color))

    def move(self):
        for particle in self.particles:
            particle.move()

    def draw(self, screen):
        for particle in self.particles:
            particle.draw(screen)

# 主循环
fireworks = []
clock = pygame.time.Clock()
done = False
while not done:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True

    # 绘制背景
    screen.blit(background, (0, 0))

    # 绘制烟花效果
    for firework in fireworks:
        firework.move()
        firework.draw(screen)
        if firework.particles[0].size < 0:
            fireworks.remove(firework)
    if random.random() < 0.1:
        fireworks.append(Firework(random.randint(0, 800), random.randint(0, 600)))

    # 刷新屏幕
    pygame.display.flip()

    # 控制帧率
    clock.tick(60)

# 退出pygame
pygame.quit()
