raise BaseException('Something is wrong here!')
Never raise BaseException directly! BaseException is the very top of the
exception hierarchy, you should raise the *most* specific exception you
can, not the least specific. BaseException isn't even just for errors,
it's also for flow control exceptions like StopIteration .
At worst, you should raise StandardError, but even that is a pretty
dodgy thing to do. In general you want something more specific, like
ValueError or TypeError. In this particular case, the appropriate error
would be to raise RuntimeError: if you're ever in the position of having
to just give up and say "I have no idea what is wrong, but something is
wrong", then RuntimeError is the one to use.
