工作需要，对公司的MysqL数据库进行备份，赶上刚刚开始学python，看了一套简单的python教学视频，简单的写了个备份脚本，个人表示 对python 的class 、function、build-in function 、私有变量、全局变量 等等，该怎么用，啥时候用等 毫无概念 ，仅此记录一下吧，也欢迎路过的pythoner赐教。
个人已知的一些问题：
1、该脚本必须要求 MysqL配置文件内的所有行为 key=value的格式，并且不能存在多余的注释，否则ConfigParser模块解析配置文件时会出错，由于没研究过ConfigParser是不是有容错的方法可以调用，也没时间写容错处理，而是通过整理my.ini 配置文件使其符合ConfigParser的要求解决的。后面会附上我用的MysqL配置文件。
2、大量使用类私有成员变量，因为完全不知道python 变量、类方法、等等啥时候该私有化，以及有啥区别，只知道类私有成员变量在别的脚本中import 或者继承时，是不可见的。
3、比较多的进行文件操作，以及传值操作，目前只保证按正确格式传值没问题，没有做多余的容错处理。 4、大量的在进行字符串拼接，第一次写运维相关脚本，由于要调用系统命令，和传递很多参数，也不会subprocess模块，不知道别人写运维脚本都具体咋做，就直接拼接了。
5、其他未知的bug、未发现的逻辑错误等等。
