我需要一个python烟花代码

以下是一个简单的Python烟花代码，可以在Python 3.x版本中运行：

import random
import time
import turtle

# 设置画布大小和背景颜色
canvas = turtle.Screen()
canvas.setup(width=600, height=600)
canvas.bgcolor("black")

# 创建烟花粒子
class Particle(turtle.Turtle):
    def __init__(self, x, y, color):
        super().__init__()
        self.penup()
        self.speed(0)
        self.color(color)
        self.goto(x, y)
        self.shape("circle")
        self.shapesize(stretch_wid=0.1, stretch_len=0.1)
        self.dx = random.uniform(-2, 2)
        self.dy = random.uniform(1, 10)
        self.gravity = 0.1
        self.life = 50

    def move(self):
        self.goto(self.xcor() + self.dx, self.ycor() + self.dy - self.gravity)
        self.dy -= self.gravity
        self.life -= 1
        if self.life <= 0:
            self.clear()

# 创建烟花
class Firework(turtle.Turtle):
    def __init__(self, x, y):
        super().__init__()
        self.penup()
        self.speed(0)
        self.color("white")
        self.goto(x, y)
        self.shape("circle")
        self.shapesize(stretch_wid=0.1, stretch_len=0.1)
        self.dy = random.uniform(5, 10)
        self.life = 100

    def move(self):
        self.goto(self.xcor(), self.ycor() + self.dy)
        self.dy -= 0.1
        self.life -= 1
        if self.life <= 0:
            self.explode()

    def explode(self):
        for i in range(50):
            p = Particle(self.xcor(), self.ycor(), random.choice(["red", "orange", "yellow", "green", "blue", "purple"]))
            particles.append(p)

        self.clear()

# 创建烟花效果
particles = []
fireworks = []
while True:
    if random.random() < 0.1:
        f = Firework(random.uniform(-250, 250), -300)
        fireworks.append(f)

    for f in fireworks:
        f.move()

    for p in particles:
        p.move()

    particles = [p for p in particles if not p.isvisible()]

    fireworks = [f for f in fireworks if not f.isvisible()]

    time.sleep(0.01)
    canvas.update()

运行该代码将在屏幕上创建一个烟花效果。每隔一段时间，会发射一个烟花并产生粒子效果。可以通过调整代码中的参数来改变烟花的数量、颜色和速度等属性。
