If you expect your software to be resilient given faulty hardware, using exceptions is not the way to do it. If the hardware is faulty, you can't rely on either the condition test (whether written with assert or not) or the recovery block to behave correctly. Hardware failure resilient software has to be designed from the very lowest levels of machine code. Given faulty hardware or cosmic-ray flipping of bits in memory, you are far more likely to get an interpreter seg fault than a failure you can test for and handle. Or an OS level failure. Machine crashing or locking up is way more likely than anything you can handle in Python. -- Steve _______________________________________________ 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/5JIFDS7DSD3F6NFNVY6TSZU4RYDJFNOE/ Code of Conduct: http://python.org/psf/codeofconduct/
