ConfigParser模块用于生成和修改常见配置文档

文件格式：

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

 

生成：

import configparserconfig = configparser.ConfigParser()config["DEFAULT"] = {
   'ServerAliveInterval': '45',           # 直接生成DEFAULT                     'Compression': 'yes',                     'CompressionLevel': '9'}config['bitbucket.org'] = {}                                # 生成空的bitbucket.orgconfig['bitbucket.org']['User'] = 'hg'                      # 再赋值config['topsecret.server.com'] = {}                         # 生成空的topsecret.server.comtopsecret = config['topsecret.server.com']                  # 再赋值topsecret['Host Port'] = '50022'  # mutates the parsertopsecret['ForwardX11'] = 'no'  # same hereconfig['DEFAULT']['ForwardX11'] = 'yes'                     # 给DEFAULT添加新内容with open('example.ini', 'w') as configfile:                # 打开文件并写入    config.write(configfile)

 

读取：

import configparserconfig = configparser.ConfigParser()print(config.sections())                        # 开始时为空config.read('example.ini')                      # 读取文件print(config.sections())                        # 不打印DEFAULTprint('\n')print('bitbucket.org' in config)                # 查找bitbucket.org是否存在print('bytebong.com' in config)print('\n')print(config['bitbucket.org']['User'])          # 读取bitbucket.org下的Userprint(config['DEFAULT']['Compression'])print('\n')topsecret = config['topsecret.server.com']print(topsecret['ForwardX11'])                  # 读取topsecret.server.com下的ForwardX11print(topsecret['host port'])print('\n')for key in config['bitbucket.org']:             # 读取bitbucket.org下所有的key(包括DEFAULT下的)    print(key)print('\n')print(config['bitbucket.org']['ForwardX11'])    # bitbucket.org下没有ForwardX11，就默认为DEFAULT下的

输出结果：

增删改查：

import configparserconfig = configparser.ConfigParser()config.read('example.ini')sec = config.remove_section('bitbucket.org')        # 删除config.remove_option('topsecret.server.com', 'host port')config.write(open('new.ini', "w"))sec = config.has_section('topsecret.server.com')    # 判断是否存在print(sec)sec = config.add_section('bytebong.com')            # 添加config.write(open('new.ini', "w"))config.set('bytebong.com', 'host port', '1111')     # 修改config.write(open('new.ini', "w"))

输出结果：

True
