אורי רודברג added the comment: 1. I think the main problem is where it's documented "first, second" while the real argument names are different. 2. I think maybe https://docs.python.org/2.7/library/unittest.html is also affected in functions such as: assertGreater(first, second, msg=None) assertGreaterEqual(first, second, msg=None) assertLess(first, second, msg=None) assertLessEqual(first, second, msg=None) ---------- versions: +Python 2.7 _______________________________________ Python tracker https://bugs.python.org/issue35676 _______________________________________

Karthikeyan Singaravelan added the comment: Thanks for the report. Looking at git history it seems there were some changes done in issue10573 to use (actual, expected) for consistency and later changed to use (first, second) in the same issue at msg126911. Discussion for the issue : https://mail.python.org/pipermail/python-dev/2010-December/106875.html I think this is a bug as seen from typeshed https://github.com/python/typeshed/pull/2724/. But I will defer it to the maintainer to take a call on the same given there was a discussion in the past. Removing versions that are on security fix only mode. I am changing the subject. Feel free to reword/revert. ---------- nosy: +ezio.melotti, xtreak title: class TestCase: docs are not correct -> unittest assert helper methods have incorrect signature in docs versions: -Python 3.4, Python 3.5, Python 3.6 _______________________________________ Python tracker https://bugs.python.org/issue35676 _______________________________________
