In particular, parse comma-separated lists where the elements of the list may include quoted-strings. A quoted-string could contain a comma. A non-quoted string could have quotes in the middle. Quotes are removed automatically after parsing. It basically works like :func:`parse_set_header` just that items may appear multiple times and case sensitivity is preserved. The return value is a standard :class:`list`: >>> parse_list_header('token, "quoted value"') ['token', 'quoted value'] To create a header from the :class:`list` again, use the :func:`dump_header` function. :param value: a string with a list header. :return: :class:`list` i i����t "( t _parse_list_headert unquote_header_valuet append( RV t resultt item( ( s> /usr/lib/python2.7/site-packages/pip/_vendor/requests/utils.pyt parse_list_header� s $c C s� i } x� t | � D]~ } d | k r5 d | | <q n | j d d � \ } } | d | d k ol d k n r� t | d d !� } n | | | <q W| S( sM Parse lists of key, value pairs as described by RFC 2068 Section 2 and convert them into a python dict: >>> d = parse_dict_header('foo="is a fish", bar="as well"') >>> type(d) is dict True >>> sorted(d.items()) [('bar', 'as well'), ('foo', 'is a fish')] If there is no value for a key it will be `None`: >>> parse_dict_header('key_without_value') {'key_without_value': None} To create a header from the :class:`dict` again, use the :func:`dump_header` function. :param value: a string with a dict header. :return: :class:`dict` t =i i����R\ N( R] R4 R> R^ ( RV R` Ra RL ( ( s> /usr/lib/python2.7/site-packages/pip/_vendor/requests/utils.pyt parse_dict_header� s $c C sq | rm | d | d k o% d k n rm | d d !} | sN | d d k rm | j d d � j d d � Sn | S( s� Unquotes a header value.
