   The PythonDocs issue is because the docstring for swaplevel is a little mangled and it breaks some of our automation:
   
   ```
   Swap levels i and j in a :class:`MultiIndex`.
   
   Default is to swap the two innermost levels of the index.
   
   Parameters
   ----------
   i, j : int or str
       Levels of the indices to be swapped. Can pass level name as string.
   axis : {0 or 'index', 1 or 'columns'}, default 0
               The axis to swap levels on. 0 or 'index' for row-wise, 1 or
               'columns' for column-wise.
   
   Returns
   -------
   DataFrame
       DataFrame with levels swapped in MultiIndex.
   
   Examples
           --------
           >>> df = pd.DataFrame(
           ...     {"Grade": ["A", "B", "A", "C"]},
           ...     index=[
           ...         ["Final exam", "Final exam", "Coursework", "Coursework"],
           ...         ["History", "Geography", "History", "Geography"],
           ...         ["January", "February", "March", "April"],
           ...     ],
           ... )
           >>> df
   ...
   ```
   
   I proposed a change upstream (https://github.com/pandas-dev/pandas/pull/44740), if that gets merged and released in 1.3.5 this issue should go away.
   
   If that takes a while or doesn't happen, we'll have to come up with some kind of workaround. I'll have to think on that. You should feel free to ignore this issue for now.
