Raymond Hettinger <raymond.hettin...@gmail.com> added the comment: I would like to leave this as-is. Consistency between error message wording is one of our least important considerations. The __getitem__ message is somewhat useful -- it helps learners know which magic method is being called and what they would need to add to a class to make it work. This was the typical wording for old-style classes. For example, calling len() on an old-style class without __len__ gave this message, "AttributeError: A instance has no attribute '__len__'".
In addition, we are getting very close to end-of-life for Python2.7. Accordingly, any changes at this point should be limited to things that really matter. It will be too easy to introduce a new problem that we won't have an opportunity to fix later. I recommend closing this and shifting attention to things that matter. ---------- assignee: -> rhettinger _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31550> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
