Maybe this is a good thing; interactive mode doesn't work in IDLE.

Apparently IDLE doesn't set sys.ps1 either:
http://bugs.python.org/issue13657 I know at least a few people who
use IDLE.... ;)
I feel like there has to be a better way to determine if an
interactive prompt is in use, though I'll admit nothing jumps
immediately to mind :/

It appears bpython does not set sys.ps1. I wonder if this shouldn't
be considered a bug/oversight in bpython though. If nothing else it
might be worth pointing out to its developers. I also wonder how this
would impact IDEs (though I don't use any personally).
