PEP8 suggests using this style of method invocation:

     obj.method(foo,
                bar,
                baz)

which is an effect impossible to do correctly with tabs alone. If you 
want to follow this style strictly, you end up having to either mix tabs 
and spaces, or just use spaces, or as I prefer it, avoid the issue 
altogether:

     obj.method(
         foo,
         bar,
         baz,
     )
