python烟花代码

以下是一个简单的 Python 烟花代码实现：

import random
import turtle

# 设置画布
turtle.setup(800, 600)
turtle.bgcolor('black')
turtle.title('烟花')

# 定义烟花粒子类
class FireworkParticle(turtle.Turtle):
    def __init__(self, x, y, color):
        turtle.Turtle.__init__(self)
        self.penup()
        self.speed(0)
        self.color(color)
        self.shape('circle')
        self.shapesize(stretch_wid=0.2, stretch_len=0.2)
        self.goto(x, y)
        self.dx = random.uniform(-2, 2)
        self.dy = random.uniform(10, 20)
        self.gravity = -0.2

    def move(self):
        self.dy += self.gravity
        self.setx(self.xcor() + self.dx)
        self.sety(self.ycor() + self.dy)

# 定义烟花类
class Firework():
    def __init__(self, x, y):
        self.particles = []
        self.color = random.choice(['red', 'orange', 'yellow', 'green', 'blue', 'purple', 'white'])
        for _ in range(50):
            self.particles.append(FireworkParticle(x, y, self.color))

    def explode(self):
        while self.particles:
            for particle in self.particles:
                particle.move()
                if particle.ycor() < 0:
                    particle.clear()
                    self.particles.remove(particle)
            turtle.update()

# 点击画布创建烟花
def create_firework(x, y):
    firework = Firework(x, y)
    firework.explode()

turtle.onscreenclick(create_firework)

# 隐藏画笔
turtle.hideturtle()

# 显示画布
turtle.done()

运行代码后，点击画布即可创建烟花。可以尝试点击多次，观察不同颜色的烟花效果。
