Ned Deily added the comment: To expand a bit, this is by design, a consequence of the hash randomization feature; see
https://docs.python.org/3/using/cmdline.html#envvar-PYTHONHASHSEED As noted there, if necessary, it is possible to disable hash randomization. But tests with set values or dict keys should not depend on a particular order as even disabling hash randomization would not guarantee the same results on different platforms or builds of Pythons. $ python3.4 -c "print(set(['A', 'B']))" {'B', 'A'} $ python3.4 -c "print(set(['A', 'B']))" {'A', 'B'} $ python3.4 -c "print(set(['A', 'B']))" {'B', 'A'} $ PYTHONHASHSEED=0 python3.4 -c "print(set(['A', 'B']))" {'B', 'A'} $ PYTHONHASHSEED=0 python3.4 -c "print(set(['A', 'B']))" {'B', 'A'} $ PYTHONHASHSEED=0 python3.4 -c "print(set(['A', 'B']))" {'B', 'A'} ---------- nosy: +ned.deily stage: -> resolved _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21691> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
