I thought that initially as well, but then I tried to manually type
"round()" at the "C-h S"s prompt, and I still get "not documented".

Then I stepped through the code, and saw that its completion candidate
list is nil.  So my current theory is that the data added by
python-mode to the DB used by info-look.el is incorrect: it should be
similar to what C Mode does.  When it does so, it should also take
into account the (bad) practice of the Python docs to follow the
function names by "()" in the index.

I believe this warrants a full bug report, with all the details.

Thanks.
