Python 烟花代码是一个有趣的编程项目，它可以通过使用图形库来生成类似于烟花效果的
图形。以下是一个简单的 Python 烟花代码示例，它使用 Pygame 库来实现：
```python
import pygame
import random
# 初始化 Pygame
pygame.init()
# 设置窗口大小
win_width = 800
win_height = 600
win = pygame.display.set_mode((win_width, win_height))
# 设置烟花粒子类
class Particle:
def __init__(self):
self.x = random.randint(0, win_width)
self.y = random.randint(0, win_height)
self.speed = random.randint(1, 5)
self.size = random.randint(2, 6)
self.color = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
def update(self):
self.x += self.speed
self.y += self.speed
if self.x > win_width or self.y > win_height:
self.x = random.randint(0, win_width)
self.y = random.randint(0, win_height)
if self.x < 0 or self.y < 0:
self.x = win_width - self.size - 1
self.y = self.size + random.randint(1, 3)
pygame.draw.circle(win, self.color, (int(self.x), int(self.y)), self.size)
# 创建烟花粒子对象列表
particles = []
for _ in range(50):
particles.append(Particle())
# 游戏主循环
running = True
while running:
