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` iit"(t_parse_list_headertunquote_header_valuetappend(RFtresulttitem((sD/tmp/pip-install-xdEqop/botocore/botocore/vendored/requests/utils.pytparse_list_headers $cCsi}xt|D]~}d|kr5d||>> 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=iiRLN(RMR&R.RN(RFRPRQR;((sD/tmp/pip-install-xdEqop/botocore/botocore/vendored/requests/utils.pytparse_dict_headers  $cCsq|rm|d|dko%dknrm|dd!}| sN|d dkrm|jddjddSn|S( sUnquotes a header value.
