Python 3 "return"

[bcatalfo]

Problem description

If you choose python 3 and just have a return statement that is just "return" as opposed to say "return foo" the "return" is not highlighted fortunately I fixed this by just adding a space so it's not a huge deal. However if you choose python (not python 3) this doesn't happen and a line that just says "return" correctly gets colored.
Please describe the issue concisely in here. In case of an error: Walk us through the steps you took to get there. What happened? What did you expect to happen?
