Exceptions in Python and C are the same. The idea with these is, either you know exactly what error to expect to handle and recover it, or you just treat it as a general error and retry, drop the result, propagate the error up, or log and abort. None of those require understanding the error.

Should an unexpected error propagate from deep down in your call stack to your current call site, do you really think that error should be handled at this specific call-site?
