python烟花代码

以下是一个简单的Python烟花代码：

import random
import time
import turtle

# 设置画布
canvas = turtle.Screen()
canvas.bgcolor("black")

# 定义烟花颜色列表
colors = ["red", "yellow", "blue", "green", "purple", "white", "orange"]

# 定义烟花
class Firework:
    def __init__(self):
        self.x = random.randint(-200, 200)
        self.y = random.randint(-200, 200)
        self.color = random.choice(colors)

    # 绘制烟花
    def explode(self):
        for i in range(30):
            particle = turtle.Turtle()
            particle.speed(0)
            particle.shape("circle")
            particle.color(self.color)
            particle.penup()
            particle.goto(self.x, self.y)
            particle.pendown()

            # 粒子爆炸效果
            explosion_speed = random.randint(1, 10)
            particle.speed(explosion_speed)

            # 粒子移动
            angle = random.uniform(0, 2 * math.pi)
            distance = random.randint(10, 200)
            x = self.x + math.sin(angle) * distance
            y = self.y + math.cos(angle) * distance
            particle.goto(x, y)

            # 清除粒子
            particle.hideturtle()

# 绘制多个烟花
for i in range(25):
    firework = Firework()
    firework.explode()

# 隐藏画笔
turtle.hideturtle()

# 显示画面
canvas.mainloop()

这个代码使用Python的turtle库绘制烟花，每次绘制一个随机位置和颜色的烟花，然后在一定时间内爆炸，发射出一些随机颜色和位置的粒子。可以根据需要自行修改和调整。
