python mysql 编程

项目心得：Python是们非常有意思的语言,之前在51cto看老男孩Python培训视频的时候看他们做的项目是采用文件存储数据和读取数据，而且界面排版我个人不是非常喜欢.我认为将数据存储在Mysql数据库中会更加完美。
项目内容：(1)Python 操作Mysql数据库的方法
          (2)Python 面向对象的编程
          (3)Python Import方法
          (4)Python 的While,Break,Continue,for if 语句结合使用
          (5)Python的列表,元组,字符串等等
大体掌握上述东西,此项目做起来就比较顺手.
同时有些方面可能没有考虑完美,也没有很多的注释,但是时间的问题,,以后会逐渐更改和完善

1.Mysql部分：
staff表

id	bigint(12)	NO	PRI	0
name	varchar(20)	NO		NULL
sex	enum('M','W')	NO		NULL
birthday	varchar(20)	NO		NULL
age	int(4)	NO		NULL
tel	bigint(12)	YES		NULL
department	varchar(6)	NO		NULL
salary	float	NO		NULL

2.部分代码：
Company.py

#!/usr/bin/python
#-*- coding:utf-8 -*-
