烟花并没有炸开的代码

非常抱歉，我的代码可能存在一些问题。以下是完整的代码，包括烟花爆炸的部分：

import turtle
import random
import time
import math

# 定义一个烟花类
class Firework:
    def __init__(self, x, y, vx, vy, ax, ay, color):
        self.x = x
        self.y = y
        self.vx = vx
        self.vy = vy
        self.ax = ax
        self.ay = ay
        self.color = color
        self.is_explode = False
        self.particles = []

    # 更新烟花粒子位置
    def update_particles(self):
        for p in self.particles:
            p.vx += p.ax
            p.vy += p.ay
            p.x += p.vx
            p.y += p.vy
            p.ttl -= 1

    # 更新烟花位置
    def update(self):
        if not self.is_explode:
            self.vy += self.ay
            self.vx += self.ax
            self.x += self.vx
            self.y += self.vy
            if self.vy <= 0:
                self.explode()

        else:
            self.update_particles()

    # 烟花爆炸
    def explode(self):
        self.is_explode = True
        for _ in range(50):
            speed = random.uniform(0.5, 1.5)
            angle = random.uniform(0, 2 * math.pi)
            vx = speed * math.cos(angle)
            vy = speed * math.sin(angle)
            p = Particle(self.x, self.y, vx, vy, -0.01, self.color)
            self.particles.append(p)

    # 判断是否烟花已经燃尽
    def is_dead(self):
        if self.is_explode:
            return all([p.ttl <= 0 for p in self.particles])
        else:
            return self.vy <= 0

# 定义一个烟花粒子类
class Particle:
    def __init__(self, x, y, vx, vy, ay, color):
        self.x = x
        self.y = y
        self.vx = vx
        self.vy = vy
        self.ay = ay
        self.ttl = random.randint(50, 80)
        self.color = color

# 实例化一个画布
canvas = turtle.Screen()

# 设置画布大小
canvas.setup(800, 600)

# 设置画笔速度
turtle.speed(0)

# 隐藏画笔
turtle.hideturtle()

# 关闭画笔轨迹
turtle.tracer(False)

# 定义烟花列表
fireworks = []

# 定义画笔颜色列表
colors = ['red', 'orange', 'yellow', 'green', 'blue', 'purple', 'white']

# 定义计数器
count = 0

# 循环绘制烟花
while True:
    # 每隔5次循环添加一个新的烟花
    if count % 5 == 0:
        x = random.randint(-400, 400)
        y = -300
        vx = random.uniform(-1, 1)
        vy = random.uniform(15, 25)
        ax = 0
        ay = -0.1
        color = random.choice(colors)
        f = Firework(x, y, vx, vy, ax, ay, color)
        fireworks.append(f)

    # 清空画布
    turtle.clear()

    # 绘制所有烟花和粒子
    for f in fireworks:
        turtle.penup()
        turtle.goto(f.x, f.y)
        turtle.pendown()
        turtle.dot(10, f.color)
        if f.is_explode:
            for p in f.particles:
                turtle.penup()
                turtle.goto(p.x, p.y)
                turtle.pendown()
                turtle.dot(5, p.color)

        # 更新烟花状态
        f.update()

        # 判断烟花是否已经燃尽
        if f.is_dead():
            fireworks.remove(f)

    # 更新画布
    turtle.update()

    # 计数器加1
    count += 1

    # 等待一段时间
    time.sleep(0.02)

希望这次能够正常运行，如果还有问题请及时告诉我。
