花里胡哨的python代码（表白+蛋糕）

学习学累了，在网上看了一个简单的代码稍微尝试了一下。真的太久没敲python了（掐指一算，两年时间弹指灰飞烟灭），现在连pycharm都要自己再装一遍，没想到pycharm要收费了。

对于python代码真的就是娱乐性质的。希望大家别过于介意

python版本 2.7 （我印象中之前的电脑是3.X版本的，但是自己太久没碰了就装了个低版本的）

下面是python安装包
https://www.python.org/ftp/python/2.7.11/python-2.7.11.msi
配置环境变量就是

此电脑->属性->高级系统设置->环境变量
系统变量的path中添加 C:/Python27

至于安装pycharm，这个我是随机在网上找资料安装的，版本好老，还没有激活。
