Detailed introduction to the Configparser module

First, Introduction

Used to generate and modify common configuration documents, the name of the current module is changed to Configparser in the Python 3.x version.

Second, the configuration file format

[DEFAULT] Serveraliveinterval = 45Compression = Yescompressionlevel = 9forwardx11 = yes [Bitbucket.org]user = HG [topsecret.server.c Om]port = 50022forwardx11 = no

　　

Iii. Creating a configuration file

Import configparser# generates a processing object, config = Configparser. Configparser ()  #默认配置 config["DEFAULT"] = {' Serveraliveinterval ': ' A ',                     ' 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 parsertopsecret[' ForwardX11 ' = ' no '  # same hereconfig[' DEFAULT ' [' ForwardX11 '] = ' yes ' #写入配置文件with open (' Example.ini ', ' W ') as ConfigFile:    config.write (ConfigFile)

　　

Iv. reading the configuration file

1. Read the node information

Import Configparserconfig = Configparser. Configparser () config.read (' Example.ini ') # reads the default configuration node information print (Config.defaults ()) #读取其他节点print (Config.sections ()) # Output ordereddict (' compression ', ' yes '), (' Serveraliveinterval ', ' a '), (' CompressionLevel ', ' 9 '), (' forwardx11 ', ' yes ') )]) [' bitbucket.org ', ' topsecret.server.com ']

　

2, the interpretation of the configuration node name exists

Print (' ssss ' in config) print (' bitbucket.org ' in config) #输出FalseTrue

　　

3. Read the information in the configuration node

Print (config[' bitbucket.org ' [' User ']) #输出hg

　　

4. Iterate through the configuration node all information

For key in config[' bitbucket.org ':    print (Key, ': ', config[' bitbucket.org '][key]) #输出user: hgcompression: Yesserveraliveinterval:45compressionlevel:9forwardx11:yes
