基础的Python烟花代码通常使用`turtle`库，而高级的Python烟花代码为了实现更逼真的效果，往往会使用`pygame`库，同时会考虑更多物理因素，如重力、空气阻力等，并且能够模拟粒子的运动和颜色变化。以下是一个使用`pygame`库的高级Python烟花代码示例： ```python import pygame import random # 初始化pygame pygame.init() # 设置屏幕大小 width, height = 800, 600 screen = pygame.display.set_mode((width, height)) pygame.display.set_caption("Fireworks") # 定义颜色 BLACK = (0, 0, 0) COLORS = [(255, 0, 0), (255, 165, 0), (255, 255, 0), (0, 128, 0), (0, 0, 255), (75, 0, 130), (238, 130, 238)] class Particle: def __init__(self, x, y, color, speed, angle): self.x = x self.y = y self.color = color self.speed = speed self.angle = angle self.gravity = 0.1 self.air_resistance = 0.98 def update(self): # 应用物理效果 self.speed *= self.air_resistance self.x += self.speed * pygame.math.Vector2().from_polar((1, self.angle))[0] self.y += self.speed * pygame.math.Vector2().from_polar((1, self.angle))[1] + self.gravity def draw(self, screen): pygame.draw.circle(screen, self.color, (int(self.x), int(self.y)), 2) class Firework: def __init__(self): self.x = random.randint(0, width) self.y = height self.color = random.choice(COLORS) self.speed = random.randint(10, 20) self.particles = [] self.exploded = False def update(self): if not self.exploded: self.y -= self.speed if self.speed <= 0: self.explode() else: for particle in self.particles[:]: particle.update() if particle.y > height: self.particles.remove(particle) def explode(self): self.exploded = True num_particles = random.randint(20, 50) for _ in range(num_particles): speed = random.randint(3, 10) angle = random.randint(0, 360) self.particles.append(Particle(self.x, self.y, self.color, speed, angle)) def draw(self, screen): if not self.exploded: pygame.draw.circle(screen, self.color, (int(self.x), int(self.y)), 5) else: for particle in self.particles: particle.draw(screen) # 创建烟花列表 fireworks = [] clock = pygame.time.Clock() running = True while running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False screen.fill(BLACK) if random.random() < 0.02: fireworks.append(Firework()) for firework in fireworks[:]: firework.update() firework.draw(screen) if firework.exploded and len(firework.particles) == 0: fireworks.remove(firework) pygame.display.flip() clock.tick(60) pygame.quit() ``` 这个代码使用`pygame`库创建了一个窗口，并在窗口中模拟烟花效果。代码中定义了`Particle`类来表示烟花爆炸后的粒子，考虑了重力和空气阻力对粒子运动的影响；同时定义了`Firework`类来表示烟花，当烟花上升到一定高度时会爆炸，产生多个粒子。
