ConfigParser模塊
用於生成和修改常見配置文檔，當前模塊的名稱在 python 3.x 版本中變更為 configparser。

來看一個好多軟件的常見文檔格式如下
[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生成一個這樣的文檔怎麽做呢？

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)
　　

寫完了還可以再讀出來哈。

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[‘Port‘]
‘50022‘
>>> for key in config[‘bitbucket.org‘]: print(key)
...
user
compressionlevel
serveraliveinterval
compression
forwardx11
>>> config[‘bitbucket.org‘][‘ForwardX11‘]
‘yes‘
configparser增刪改查語法

[section1]
k1 = v1
k2:v2

[section2]
k1 = v1

import ConfigParser

config = ConfigParser.ConfigParser()
config.read(‘i.cfg‘)

# ########## 讀 ##########
#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‘)

# ########## 改寫 ##########
#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"))
