今天给大家分享2个烟花效果代码

希望大家平平安安，身体健康！

并且是第一次在这里创作！

1.ui类

if __name__ == '__main__':
    root = tk.Tk()
    app = FireworksApp(root)
    root.mainloop()

这个代码不需要外部库——它只使用tkinter（内置于Python中）。以下是它的特点：

有烟花发射的效果，并且很不错！
 

效果:

2.使用turtle

代码:

import turtle
import random
import time

t = turtle.Turtle()
t.speed(0)
t.hideturtle()
turtle.bgcolor("black")

colors = ["red", "yellow", "blue", "purple", "orange", "cyan", "white"]

def firework(x, y):
    t.penup()
    t.goto(x, y)
    t.pendown()

    color = random.choice(colors)
    t.color(color)

    for _ in range(36):
        t.forward(random.randint(50, 100))
        t.backward(random.randint(50, 100))
        t.right(10)

while True:
    x = random.randint(-300, 300)
    y = random.randint(-200, 200)
    firework(x, y)
    time.sleep(0.5)

这个代码无需安装任何库，Python 自带
👉 原理清晰，适合学习

注意这个代码是无限循环的！

效果:
