Yeah, it's an oddly named method. But I can't think of any name for it
that isn't odd.
I was just writing up a reply when your third message came in, but
there's one small aspect that's still worth mentioning, so I'll quote
it.

Yes, that would be the right method to use. I'd not bother with the
function and map() though, and simply iterate:
d = {}
for val in l:
d.setdefault(f(val), []).append(val)
Enjoy!
