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:

self.initial_speed = explosion_speed

二、动态樱花
效果如下：
代码如下：

if (0, 1) == 0:
('snow')
else:
('lightcoral') # 淡珊瑚色
(branch / 2)
else:
('sienna') # 赭(zhě)色
(branch / 10) # 6
(branch)
a = 1.5 * ()
(20 * a)
b = 1.5 * ()
Tree(branch - 10 * b, t)
(40 * a)
Tree(branch - 10 * b, t)
(20 * a)
()
(branch)
()
# 掉落的花瓣
def Petal(m, t):
for i in range(m):
a = 200 - 400 * ()
b = 10 - 20 * ()
()
(b)
(90)
(a)
()
('lightcoral') # 淡珊瑚色
(1)
()
(a)
(90)
(b)
# 绘图区域
t = ()
# 画布大小
w = ()
() # 隐藏画笔
().tracer(5, 0)
(bg='wheat') # wheat小麦
(90)
()
(150)
()
