option 1:

url_dicts, url_args = url_check.groupdict(), url_check.groups()
if url_dicts:
  do_thing(**url_dicts)
else:
  do_thing(*url_args)

option 2:

url_arguments = url_check.groupdict() or url_check.groups()
if isinstance(url_arguments, dict):
  do_thing(**url_arguments)
else:
  do_thing(*url_arguments)

My mental ordering always thinks of args before kwargs, due to how they're used in functions.

url_args, url_dicts = url_check.groups(), url_check.groupdict()
if url_args:
    do_thing(*url_args)
else:
    do_thing(**url_dicts)

Current

if not hasattr(self, '_url_args') or self._url_args is None:
                self._url_args = []

            rendered = fun(*self._url_args)

changes to

         if not hasattr(self, '_url_args') or self._url_args is None:
                self._url_args = []
            if isinstance(self._url_args, dict):
                rendered = fun(**self._url_args)
            else:
                rendered = fun(*self._url_args)
