生成一段烟花绽放的代码

下面是一段使用Python Turtle库生成烟花绽放的代码：

import turtle
import random

# 设置画布大小和背景颜色
canvas = turtle.Screen()
canvas.setup(800, 600)
canvas.bgcolor("#000000")

# 创建烟花粒子的类
class Particle(turtle.Turtle):
    def __init__(self):
        turtle.Turtle.__init__(self, visible=False)
        self.speed(0)
        self.penup()
        self.color("white")
        self.shape("circle")
        self.shapesize(stretch_wid=0.1, stretch_len=0.1)
        self.goto(0, 0)
        self.showturtle()

    # 粒子移动的方法
    def move(self):
        self.x += self.dx
        self.y += self.dy - self.gravity
        self.goto(self.x, self.y)
        self.dy -= self.gravity

    # 判断粒子是否在画布内的方法
    def is_inside(self):
        x, y = self.pos()
        if abs(x) > canvas.window_width() / 2 or abs(y) > canvas.window_height() / 2:
            return False
        else:
            return True

# 创建烟花的方法
def create_firework(x, y):
    # 设置烟花的颜色和数量
    colors = ["red", "orange", "yellow", "green", "blue", "purple", "white"]
    num_particles = 100

    # 创建烟花粒子
    particles = []
    for i in range(num_particles):
        particle = Particle()
        particle.x = x
        particle.y = y
        particle.gravity = 0.05
        particle.setheading(random.randint(0, 360))
        particle.color(random.choice(colors))
        particle.speed(random.randint(1, 10))
        particle.dx = particle.speed() * math.cos(particle.heading() * math.pi / 180.0)
        particle.dy = particle.speed() * math.sin(particle.heading() * math.pi / 180.0)
        particles.append(particle)

    # 让粒子移动并绘制烟花
    while any(p.is_inside() for p in particles):
        for particle in particles:
            particle.move()
        canvas.update()

    # 隐藏烟花粒子
    for particle in particles:
        particle.hideturtle()

# 注册鼠标点击事件
canvas.onclick(create_firework)

# 启动画布主循环
canvas.mainloop()

运行上面的代码，然后在画布上点击鼠标，就可以生成一朵绚丽的烟花了！
