Python开发转盘小游戏

Python开发转盘小游戏

Python 

一 原理分析

1. Python开发一个图形界面
2. 有12个选项和2个功能键
3. 确定每个按钮的位置
   每个按钮的间隔相同
4. 点击开始时转动，当前选项的背景颜色为红色，其他为白色

二 知识点与难点

2.1 使用的package

1. tkinter
   Python内置，实现GUI的主要package
2. threading
   实现多线程实现循环
3. time
   用来延时

2.2 注意点

1. 判断类型时使用isinstance函数，不要用type，因为type不区分子类
2. 判断变量是否为TRUE，FALSE，None时要用is不要用==
3. 循环时记得处理自增时超过下标时的归零
4. tkinter下面的按钮属性可以通过键值赋值改变属性
5. 全局变量
