        expand('https://api.github.com{/end}', end='gists')

    .. note:: Passing values by both parts, may override values in
              ``var_dict``. For example::

                  expand('https://{var}', {'var': 'val1'}, var='val2')

              ``val2`` will be used instead of ``val1``.
