练习内容:
使用Python管理ini文件:实现查询,添加,删除,保存操作。
练习目的:
1.掌握文件基本操作
2.认识ini文件
3.了解ConfigParser;
ini配置文件格式:

cfg.read(‘test.txt‘)
cfg.sections()
cfg.items
for se in cfg.sections():
print se
print cfg.items(se)
cfg.set(‘userinfo‘,‘pwd‘,‘passw0rd‘):修改
cfg.set(‘userinfo‘,‘email‘,‘[email protected]‘):插入
cfg.remove_option(‘userinfo‘,‘email‘)
