Similar question: What would be the semantics of this?with contextlib.suppress(BaseException): a = b / c except BaseException as e: print(e) What types of exception could be caught and what types couldn't?
Well, if every exception is derived from BaseException (they are) and contextlib.suppress(BaseException) suppresses all BaseException-derived exceptions (it does) then the semantics of the above are:
- "a" will be the result of "b / c" if no exception occurs - otherwise, "a" will be whatever it was before the with-block - no exception will ever be caught by the except-clause Generally speaking, no exception that a context manager handles (i.e. suppresses) will ever be available to be caught. -- ~Ethan~ _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/6MECZSWSSBIJUTZQWLKSCJKO7PRZA5WT/ Code of Conduct: http://python.org/psf/codeofconduct/
