标准库模块：ConfigParse

Posted 2020-11-04 q1ang

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。

常见文档格式

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

conf

文档生成

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)

　　文档读、改、删

import configparser
config = configparser.ConfigParser()

config.read(‘example.ini‘)

print(config.sections())  #只打印节点
#增
print(config[‘bitbucket.org‘][‘user‘])
#改
sec=config.remove_section(‘bitbucket.org‘)
config.write(open(‘example.cfg‘,‘w‘))
