As the example above shows, the add_argument() method is used to populate the parser with actions for optional and positional arguments. Then the parse_args() method is invoked to convert the args at the command-line into an object with attributes. - ArgumentError -- The exception raised by ArgumentParser objects when there are errors with the parser's actions. Errors raised while parsing the command-line are caught by ArgumentParser and emitted as command-line messages. - FileType -- A factory for defining types of files to be created. As the example above shows, instances of FileType are typically passed as the type= argument of add_argument() calls. - Action -- The base class for parser actions. Typically actions are selected by passing strings like 'store_true' or 'append_const' to the action= argument of add_argument(). However, for greater customization of ArgumentParser actions, subclasses of Action may be defined and passed as the action= argument. - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter, ArgumentDefaultsHelpFormatter -- Formatter classes which may be passed as the formatter_class= argument to the ArgumentParser constructor. HelpFormatter is the default, RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser not to change the formatting for help text, and ArgumentDefaultsHelpFormatter adds information about argument defaults to the help. All other classes in this module are considered implementation details. (Also note that HelpFormatter and RawDescriptionHelpFormatter are only considered public as object names -- the API of the formatter objects is still considered an implementation detail.) z1.1�ArgumentParser� ArgumentError�ArgumentTypeError�FileType� HelpFormatter�ArgumentDefaultsHelpFormatter�RawDescriptionHelpFormatter�RawTextHelpFormatter�MetavarTypeHelpFormatter� Namespace�Action�ONE_OR_MORE�OPTIONAL�PARSER� REMAINDER�SUPPRESS�ZERO_OR_MORE�N)�gettext�ngettextz==SUPPRESS==�?�*�+zA...z...Z_unrecognized_argsc@s(eZdZdZdd�Zdd�Zdd�ZdS) �_AttributeHolderaAbstract base class that provides __repr__.
