I could not repeat the timing results on my machine running from the command line, as I got '0.015 usec per loop' for both, and same for both frozenset variations. Running timeit.repeat interactively and selecting the best reproduced your timing ratio: .16 to .42. For frozenset, I get .36 to .42 in favor of changing to frozenset({...}). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22823> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
