1.來看一個好多軟體的常見文檔格式如下：

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

如果想用python產生一個這樣的文檔怎麼做呢？

import configparserconfig = configparser.ConfigParser()config["DEFAULT"] = {‘ServerAliveInterval‘: ‘45‘,                      ‘Compression‘: ‘yes‘,                     ‘CompressionLevel‘: ‘9‘,                     ‘ForwardX11‘:‘yes‘                     }config[‘bitbucket.org‘] = {‘User‘:‘hg‘}config[‘topsecret.server.com‘] = {‘Host Port‘:‘50022‘,‘ForwardX11‘:‘no‘}with open(‘example.ini‘, ‘w‘) as configfile:   config.write(configfile)

尋找檔案

import configparserconfig = configparser.ConfigParser()#---------------------------尋找檔案內容,基於字典的形式print(config.sections())        #  []config.read(‘example.ini‘)print(config.sections())        #   [‘bitbucket.org‘, ‘topsecret.server.com‘]print(‘bytebong.com‘ in config) # Falseprint(‘bitbucket.org‘ in config) # Trueprint(config[‘bitbucket.org‘]["user"])  # hgprint(config[‘DEFAULT‘][‘Compression‘]) #yesprint(config[‘topsecret.server.com‘][‘ForwardX11‘])  #noprint(config[‘bitbucket.org‘])          #<Section: bitbucket.org>for key in config[‘bitbucket.org‘]:     # 注意,有default會預設default的鍵    print(key)print(config.options(‘bitbucket.org‘))  # 同for迴圈,找到‘bitbucket.org‘下所有鍵print(config.items(‘bitbucket.org‘))    #找到‘bitbucket.org‘下所有索引值對print(config.get(‘bitbucket.org‘,‘compression‘)) # yes       get方法Section下的key對應的value

增刪改操作

import configparserconfig = configparser.ConfigParser()config.read(‘example.ini‘)config.add_section(‘yuan‘)config.remove_section(‘bitbucket.org‘)config.remove_option(‘topsecret.server.com‘,"forwardx11")config.set(‘topsecret.server.com‘,‘k1‘,‘11111‘)config.set(‘yuan‘,‘k2‘,‘22222‘)config.write(open(‘new2.ini‘, "w"))
