显着无聊收集了下用python绘制烟花，绘制樱花，烟花+樱花，飘零雪花，玫瑰花的python绘制代码，可以来练手什么的哦。

同时python实现八音符，坦克大战，贪吃蛇，FlappyBird等都可以参考哦=> code

一、python实现烟花

效果图：

代码如下 ：

import tkinter as tk

from PIL import Image, ImageTk

from time import time, sleep

from random import choice, uniform, randint

from math import sin, cos, radians

# 模拟重力

GRAVITY = 0.05

# 颜色选项(随机或者按顺序)

colors = ['red', 'blue', 'yellow', 'white', 'green', 'orange', 'purple', 'seagreen', 'indigo', 'cornflowerblue']

'''

particles 类

粒子在空中随机生成随机，变成一个圈、下坠、消失

属性:

- id: 粒子的id

- x, y: 粒子的坐标

- vx, vy: 在坐标的变化速度

- total: 总数

- age: 粒子存在的时长

- color: 颜色

- cv: 画布

- lifespan: 最高存在时长

'''

class Particle:

def __init__(self, cv, idx, total, explosion_speed, x=0., y=0., vx=0., vy=0., size=2., color='red', lifespan=2,

**kwargs):

self.id = idx

self.x = x

self.y = y

self.initial_speed = explosion_speed

self.vx = vx

self.vy = vy

self.total = total

self.age = 0

self.color = color

self.cv = cv

self.cid = self.cv.create_oval(

x - size, y - size, x + size,

y + size, fill=self.color)

self.lifespan = lifespan

def update(self, dt):

self.age += dt

# 粒子范围扩大

if self.alive() and self.expand():

move_x = cos(radians(self.id * 360 / self.total)) * self.initial_speed

move_y = sin(radians(self.id * 360 / self.total)) * self.initial_speed

self.cv.move(self.cid, move_x, move_y)

self.vx = move_x / (float(dt) * 1000)

# 以自由落体坠落

elif self.alive():

move_x = cos(radians(self.id * 360 / self.total))

# we technically don't need to update x, y because move will do the job

self.cv.move(self.cid, self.vx + move_x, self.vy + GRAVITY * dt)

self.vy += GRAVITY * dt

# 移除超过最高时长的粒子

elif self.cid is not None:

cv.delete(self.cid)

self.cid = None

# 扩大的时间

def expand (self):

return self.age <= 1.2

# 粒子是否在最高存在时长内

def alive(self):

return self.age <= self.lifespan

'''

二、动态樱花
