Python函数和常用模块-ConfigParser模块

常见配置文件格式：

[DEFAULT]
ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes
[hantao.org]
User = ht
[firewall]
Port = 50022
ForwardX11 = no

生成配置文件：

import configparser
config = configparser.ConfigParser()
config["DEFAULT"] = {'ServerAliveInterval': '45',
                      'Compression': 'yes',
                     'CompressionLevel': '9'}
config['hantao.org'] = {}
config['hantao.org']['User'] = 'hg'
config['firewall'] = {}
topsecret = config['firewall']
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)

配置文件读取：

import configparser
config = configparser.ConfigParser()
config.read('example.ini')
config.sections()#查看节点
config['hantao.org']['User']#查看节点参数

增删改：

[section1]
k1 = v1
k2:v2
[section2]
k1 = v1
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"))
