Python中配置文件编写configparser
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。
来看一个好多软件的常见文档格式如下

[DEFAULT] ServerAliveInterval = 45 Compression = yes CompressionLevel = 9 ForwardX11 = yes [bitbucket.org] User = hg [topsecret.server.com] Port = 50022 ForwardX11 = no |
如果想用python生成一个这样的文档怎么做呢?

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) |
写完了还可以再读出来哈。
