Configparser module: for creating profiles in a certain format

Create

ImportConfigparserconfig=Configparser. Configparser () config['DEFAULT'] = {'default':'Yes'}config['Path'] = {'UserInfo': R'E:\pycharm\ Learning \day29\userinfo'}with Open ('Userinfo.ini','W', encoding='Utf-8') as F:config.write (f)

After the file is completed:

== E:\pycharm\ Learning \day29\userinfo

View

Print(Config.sections ())#[] Because the file has not yet been readConfig.read ('Userinfo.ini', encoding='Utf-8')Print(Config.sections ())#[' path '] read out node [' Default '] for default node not printingPrint('Path' inchConfig#True to determine if a node is in the configuration filePrint(config['Path']['UserInfo'])#E:\pycharm\ Learning \day29\userinfo The configuration item under the Read node no such target errorPrint(Config.get ('Path','UserInfo'))#E:\pycharm\ Learning \day29\userinfo forKinchconfig['Path']:#Printing the configuration items under the ' Path ' node also prints all the items under the default node    Print(k)#userinfo DefaultPrint(Config.items ('Path'))#[(' Default ', ' Yes '), (' UserInfo ', ' e:\\pycharm\\ Learning \\day29\\userinfo ')]

Increase
