Hmm, my original reply didn't show up.

I'm curious as to what you're trying to accomplish.

Bear in mind that I type this response not knowing your application.
While Python is not a statically typed language, 0 and False are
essentially different types (int and bool).  Storing them both as keys
of a dictionary just doesn't seem like a good design.
