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( e Zd ZdZdd� Zdd� Zdd� ZdS ) �_AttributeHoldera Abstract base class that provides __repr__.

Action objects are used by an ArgumentParser to represent the information needed to parse a single argument from one or more strings from the command line. The keyword arguments to the Action constructor are also all attributes of Action instances. Keyword Arguments: - option_strings -- A list of command-line option strings which should be associated with this action. - dest -- The name of the attribute to hold the created object(s) - nargs -- The number of command-line arguments that should be consumed. By default, one argument will be consumed and a single value will be produced. Other values include: - N (an integer) consumes N arguments (and produces a list) - '?' consumes zero or one arguments - '*' consumes zero or more arguments (and produces a list) - '+' consumes one or more arguments (and produces a list) Note that the difference between the default and nargs=1 is that with the default, a single value will be produced, while with nargs=1, a list containing a single value will be produced. - const -- The value to be produced if the option is specified and the option uses an action that takes no values. - default -- The value to be produced if the option is not specified. - type -- A callable that accepts a single string argument, and returns the converted value. The standard Python types str, int, float, and complex are useful examples of such callables. If None, str is used. - choices -- A container of values that should be allowed. If not None, after a command-line argument has been converted to the appropriate type, an exception will be raised if it is not a member of this collection. - required -- True if the action must always be specified at the command line. This is only meaningful for optional command-line arguments. - help -- The help string describing the argument. - metavar -- The name to be used for the option's argument with the help string. If None, the 'dest' value will be used as the name.
