    Create and return a SAX :class:`~xml.sax.xmlreader.XMLReader` object.  The
    first parser found will
-   be used.  If *parser_list* is provided, it must be a sequence of strings which
+   be used.  If *parser_list* is provided, it must be an iterable of strings which
    name modules that have a function named :func:`create_parser`.  Modules listed
    in *parser_list* will be used before modules in the default list of parsers.
 
+   .. versionchanged:: 3.8
+      The *parser_list* argument can be any iterable, not just a list.
