Python configparser模块

Python 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。

• 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

用python生成一个上述的文档

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)

• example.ini文件

[DEFAULT]
ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes

[bitbucket.org]
User = hg

[topsecret.server.com]
Port = 50022
ForwardX11 = no

读取配置文件

>>> import configparser
>>> config = configparser.ConfigParser()
>>> config.sections()
[]
>>> config.read('example.ini')
['example.ini']
>>> config.defaults()
OrderedDict([('serveraliveinterval','45'),('compression','yes'),('compressionlevel','9'),('forwardX11','yes')])
>>> 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 增删改查语法

# 数据
[section1]
k1 = v1
k2:v2
   
[section2]
k1 = v1

# python文件
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"))
