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:

python代码樱花落下 python代码画樱花飘落_Image

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
