People are going to skip warning boxes if they occur too often.
I'm not sure I agree. This would be true if they were abused for trivial things ("Warnings: using .pop() on a empty list will return an IndexError!"), but I don't think they are. I think warnings are ignored only by people that are already familiar with the module and its limitation/issues, and that know what they are doing. If the warning is not evident, people are going to miss it [0]. If warnings are used correctly, people will spot them easily and read them (or ignore them if they already know what they are warning against). [0]: I know I missed it in e.g. https://api.jquery.com/die/ -- the function is deprecated, but (currently) this is only written in the top right corner and in small in the category at the top -- two places that are easily overlooked. https://api.jquery.com/toggle-event/ on the other hand has a clearly visible yellow box at the top that immediately says that the method is deprecated. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue17006> _______________________________________
