此模块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配置文件格式如下

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

解析配置文件

>>> import configparser
>>> config = configparser.ConfigParser() >>> config.sections() [] >>> config.read('example.ini') ['example.ini'] >>> config.sections() ['bitbucket.org', 'topsecret.server.com'] >>> 'bitbucket.org' in config True >>> 'bytebong.com' in config False >>> config['bitbucket.org']['User'] 'hg' >>> config['DEFAULT']['Compression'] 'yes' >>> topsecret = config['topsecret.server.com'] >>> topsecret['ForwardX11'] 'no' >>> topsecret['Port'] '50022' >>> for key in config['bitbucket.org']: print(key) ... user compressionlevel serveraliveinterval compression forwardx11 >>> config['bitbucket.org']['ForwardX11'] 'yes' 

其它增删改查语法

[group1]
k1 = v1
k2:v2[group2]
k1 = v1import ConfigParserconfig = ConfigParser.ConfigParser()
config.read('i.cfg')# ########## 读 ##########
#secs = config.sections()
#print secs
#options = config.options('group2')
#print options#item_list = config.items('group2')
#print item_list#val = config.get('group1','key')
#val = config.getint('group1','key')

# ########## 改写 ##########

import configparserconfig = configparser.ConfigParser()config.read('test.ini')

# sec = config.remove_section('group1')# config.write(open('i.cfg', 'w'))

# sec = config.has_section('wupeiqi')# print(sec)# sec = config.add_section('wupeiqi')# config.write(open('i.cfg', 'w'))

# config.set('group2', 'k1', '111111')# config.write(open('i.cfg', 'w'))

config.remove_option('group2', 'k3')config.write(open('i.cfg', 'w'))
