1. Introduction

Used to generate and modify common configuration documents. The name of the current module was changed to configparser in the python 3.x version.

2. Configuration file format

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

 

3. Create configuration file

import configparser

# 生成一个处理对象
config = configparser.ConfigParser()  
#默认配置 
config["DEFAULT"] = {'ServerAliveInterval': '45',
                     'Compression': 'yes',
                     'CompressionLevel': '9'}

#生成其他的配置组
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'

#写入配置文件
with open('example.ini', 'w') as configfile:
    config.write(configfile)

 

4. Read the configuration file

1. Read the node information

import configparser

config = configparser.ConfigParser()
config.read('example.ini')

# 读取默认配置节点信息
print(config.defaults())

#读取其他节点
print(config.sections())

# 输出
OrderedDict([('compression', 'yes'), ('serveraliveinterval', '45'), ('compressionlevel', '9'), ('forwardx11', 'yes')])

['bitbucket.org', 'topsecret.server.com']

 

2. Determine whether the configuration node name exists

print('ssss' in config)
print('bitbucket.org' in config)

#输出
False
True

 

3. Read the information in the configuration node

print(config['bitbucket.org']['user'])

#输出

hg

 

4. Loop to read all the information of the configuration node

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

#输出

user : hg
compression : yes
serveraliveinterval : 45
compressionlevel : 9
forwardx11 : yes
