用于生成和修改常见配置文档，当前模块的名称在 python 3.x 版本中变更为 configparser。
来看一个好多软件的常见文档格式如下

[DEFAULT]ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes
[bitbucket.org]User = hg
[topsecret.server.com]Port = 50022
ForwardX11 = no

如果想用python生成一个这样的文档怎么做呢？

import configparser
config = configparser.ConfigParser()
config["DEFAULT"] = {'ServerAliveInterval': '45',
'Compression': 'yes',
'CompressionLevel': '9'}
config['bitbucket.org'] = {}
config['bitbucket.org']['User'] = 'hg'
config['topsecret.server.com'] = {}
topsecret = config['topsecret.server.com']
topsecret['Host Port'] = '50022' # mutates the parser
topsecret['ForwardX11'] = 'no' # same here
config['DEFAULT']['ForwardX11'] = 'yes'
with open('example.ini', 'w') as configfile:
config.write(configfile)

写完了还可以再读出来哈。
