python小白-day6 ConfigParser模块

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

用python生成上文档代码如下;

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

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)

读文档：

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['Port'] '50022' >>> for key in config['bitbucket.org']: print(key) ... user compressionlevel serveraliveinterval compression forwardx11 >>> config['bitbucket.org']['ForwardX11'] 'yes'

删除bitbucket.org：

1 2 3 4 5 6

import configparser   config = configparser.ConfigParser() config.read('example.ini') config.remove_section('bitbucket.org') config.write(open('example.bak','w'))

增加hetan：

1 2 3 4 5 6 7 8

import configparser   config = configparser.ConfigParser() config.read('example.ini') config.has_section('hetan') config.add_section('hetan') config['hetan']['age'] = "26" config.write(open('example.cfg','w'))

修改hetan中的age为25：

1 2 3 4 5 6

import configparser   config = configparser.ConfigParser() config.read('example.cfg') config.set('hetan','age','25') config.write(open('example.cfg.bak','w'))

删除hetan中的age：

1 2 3 4 5 6

import configparser   config = configparser.ConfigParser() config.read('example.cfg.bak') config.remove_option('hetan','age') config.write(open('example.cfg.bak2','w'))
