前言
嗨喽，大家好呀~这里是爱看美女的茜茜呐
又到了学Python时刻~
; 准备
准备一下你运行效果的背景图
以及一首你喜欢或那你女朋友喜欢的音乐
效果
; 代码展示
导入模块
import random
import pygame as py
import tkinter as tk
from time import time, sleep
from tkinter import filedialog
from PIL import Image, ImageTk
from math import sin, cos, radians
from random import choice, uniform, randint
生成随机颜色
def randomcolor():
colArr = ['1','2','3','4','5','6','7','8','9','A','B','C','D','E','F']
color = ""
for i in range(6):
color += colArr[random.randint(0,14)]
return "#"+color
重力变量
GRAVITY = 0.06
颜色列表
colors = ['red', 'blue', 'yellow', 'white', 'green', 'orange', 'purple', 'seagreen','indigo', 'cornflowerblue', 'pink']
”’
Generic class for particles
particles are emitted almost randomly on the sky, forming a round of circle (a star) before falling and getting removed
from canvas
Attributes（属性）:
- id: 粒子的id
- x, y: 粒子的坐标
- vx, vy: 粒子在对应坐标的变化速度
- total:一颗烟花里的粒子总数
- age: 粒子在画布上停留的时间
- color: 自我移植
- cv: 画布
- lifespan: 粒子在画布上停留的时间

PS：本篇完整源码如有需要的小伙伴可以加下方的群去找管理员免费领取
为每一个烟花绽放出来的粒子单独构建一个类的对象 ，
每个粒子都会有一些重要的属性，决定它的外观（大小、颜色）、移动速度等
class part:

每个烟花的特定标识符

烟花绽放x轴

烟花绽放y轴

粒子运动x轴速度

绽放粒子数

粒子已停留时间
self.age = 0
粒子颜色
self.color = color
画布
self.cv = cv
指定一个限定矩形（Tkinter 会自动在这个矩形内绘制一个椭圆）
self.cid = self.cv.create_oval(x - size, y - size, x + size,y + size, fill=self.color, outline='white',width=0.01)
