python模块之configparser模块
configparser
该模块适用于配置文件的格式与windows ini文件类似,可以包含一个或多个节(section),每个节可以有多个参数(键=值)
创建文件

[DEFAULT] ServerAliveInterval = 45 Compression = yes CompressionLevel = 9 ForwardX11 = yes [bitbucket.org] User = hg [topsecret.server.com] Port = 50022 ForwardX11 = no
import configparser config = 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)
查找文件
import configparser config = configparser.ConfigParser() #---------------------------查找文件内容,基于字典的形式 print(config.sections()) # [] config.read('example.ini') print(config.sections()) # ['bitbucket.org', 'topsecret.server.com'] print('bytebong.com' in config) # False print('bitbucket.org' in config) # True print(config['bitbucket.org']["user"]) # hg print(config['DEFAULT']['Compression']) #yes print(config['topsecret.server.com']['ForwardX11']) #no print(config['bitbucket.org']) #<Section: bitbucket.org> for key in config['bitbucket.org']: # 注意,有default会默认default的键 print(key) print(config.options('bitbucket.org')) # 同for循环,找到'bitbucket.org'下所有键 print(config.items('bitbucket.org')) #找到'bitbucket.org'下所有键值对 print(config.get('bitbucket.org','compression')) # yes get方法Section下的key对应的value
增删改操作
import configparser config = configparser.ConfigParser() config.read('example.ini') config.add_section('yuan') # 添加节 config.remove_section('bitbucket.org') # 删除节 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"))
