A quoted-string could 95 contain a comma. A non-quoted string could have quotes in the 96 middle. Quotes are removed automatically after parsing. 97 98 It basically works like :func:`parse_set_header` just that items 99 may appear multiple times and case sensitivity is preserved. 100 101 The return value is a standard :class:`list`: 102 103 >>> parse_list_header('token, "quoted value"') 104 ['token', 'quoted value'] 105 106 To create a header from the :class:`list` again, use the 107 :func:`dump_header` function. 108 109 :param value: a string with a list header. 110 :return: :class:`list` 111 :rtype: list 112 Nr rp �")�_parse_list_header�unquote_header_value�append)r� �result�itemr> r> r? �parse_list_headerm s ( r� c C sx i }t | �D ]3}d|vrd||< q|�dd�\}} | dd� | dd� kr+dkr5n nt| dd� �} | ||< q|S )a^ Parse lists of key, value pairs as described by RFC 2068 Section 2 and 113 convert them into a python dict: 114 115 >>> d = parse_dict_header('foo="is a fish", bar="as well"') 116 >>> type(d) is dict 117 True 118 >>> sorted(d.items()) 119 [('bar', 'as well'), ('foo', 'is a fish')] 120 121 If there is no value for a key it will be `None`: 122 123 >>> parse_dict_header('key_without_value') 124 {'key_without_value': None} 125 126 To create a header from the :class:`dict` again, use the 127 :func:`dump_header` function. 128 129 :param value: a string with a dict header. 130 :return: :class:`dict` 131 :rtype: dict 132 �=Nr rp r� )r� r4 r� )r� r� r� rn r> r> r? �parse_dict_header� s ( 133 r� c C s^ | r-| d | d krdkr-n | S | dd� } |r#| dd� dkr-| � dd�� d d�S | S ) 134 z�Unquotes a header value.
