标准库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。

来看一个好多软件的常见文档格式如下：

1 2 3 4 5 6 7 8 9 10 11 12

[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？

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

import configparser #in Python 2.x 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 '上面注释的部分和下面的方法等价' config['topsecret.server.com']['Host Port']='50022' config['topsecret.server.com']['ForwardX11']='no' config['DEFAULT']['ForwardX11'] = 'yes' #这边是对上面的DEFAULT追加了一条记录 with open('example.ini', 'w') as configfile: config.write(configfile)

写完了还可以再读出来哈。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

>>> import configparser >>> config = configparser.ConfigParser() >>> config.sections() [] >>> config.read('example.ini') ['example.ini'] >>> 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['Host 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
