标准库ConfigParser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  #in Python 2.x 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
'上面注释的部分和下面的方法等价'
config['topsecret.server.com']['Host Port']='50022'
config['topsecret.server.com']['ForwardX11']='no'

config['DEFAULT']['ForwardX11'] = 'yes' #这边是对上面的DEFAULT追加了一条记录

with open('example.ini', 'w') as configfile:
    config.write(configfile)

写完了还可以再读出来哈。

>>> 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['Host Port']

'50022'

>>> for key in config['bitbucket.org']: print(key)

...

user

compressionlevel

serveraliveinterval

compression

forwardx11

>>> config['bitbucket.org']['ForwardX11']

'yes'

configparser增删改查语法

[section1]

k1 = v1

k2:v2

[section2]

k1 = v1

#以上为配置文件显示的结构

import ConfigParser

config = 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 ##########

#sec = config.remove_section('group1')

#config.write(open('i.cfg', "w"))

#sec = config.has_section('wupeiqi')

#sec = config.add_section('wupeiqi')

#config.write(open('i.cfg', "w"))

#config.set('group2','k1',11111)

#config.write(open('i.cfg', "w"))

#config.remove_option('group2','age')

#config.write(open('i.cfg', "w"))
