The Booleans can be represented as string, in order to accept Boolean value from the command line arguments. If the key `optname` is present in the dictionary `options` and is not associated with a Boolean, raise an `OptionError`. If it is absent, `default` is returned instead. The valid string values for ``True`` are ``1``, ``yes``, ``true`` and ``on``, the ones for ``False`` are ``0``, ``no``, ``false`` and ``off`` (matched case-insensitively). zBInvalid type %r for option %s; use 1/0, yes/no, true/false, on/off)�1�yes�true�onT)�0�no�false�offFzCInvalid value %r for option %s; use 1/0, yes/no, true/false, on/offN)r � isinstance�bool�intr r r �r r r r r r r � get_bool_opt6 s$ �� ��r$ c C s^ | � ||�}z t|�W S ty8 td||f ��Y n" tyX td||f ��Y n0 dS )z?As :func:`get_bool_opt`, but interpret the value as an integer.z=Invalid type %r for option %s; you must give an integer valuez>Invalid value %r for option %s; you must give an integer valueN)r r" � TypeErrorr � ValueErrorr# r r r � get_int_optU s �� ��r' c C sH | � ||�}t|t�r |�� S t|ttf�r4t|�S td||f ��dS )z� If the key `optname` from the dictionary `options` is a string, split it at whitespace and return it.
