In addition to what others have written, I will add one thing. There are certainly situations where raising an exception is bad. Consider all the people in the scientific computing community doing fancy linear algebra sorts of things, often with missing data. They generally want NaN propagated and not have some long running calculation crash in the middle. Skip -- https://mail.python.org/mailman/listinfo/python-list
