The only thing that strikes me as a bit odd, is that the last bit if given as '~/checkForward.py in out_of_bounds()', while the actual function seems to be called outOfBounds(). I don't know this traceback (ie, I can't tell what Python environment/editor you're using), but that could suggest the byte-compiled code you are running doesn't match with the actual current code. 
So you may have changed the function name in the meantime, *as well as* fixed a parenthesis in the process. But perhaps you haven't then recompiled your current code, and for some reason your Python executable hasn't picked up the most recent source code and recompiled that for you. 
If this is the case, it may be dependent on your development environment that does this (somewhat incorrectly, assuming you have at least saved the source file), but as I mentioned, I have no idea what you're using.

Then again, this is still a guess. But it's the only thing I can see that stands out.

Cheers,
