Terry J. Reedy <tjre...@udel.edu> added the comment: 3 years ago, Trey Hunter found 11 ways to merge to a new dict. https://treyhunner.com/2016/02/how-to-merge-dictionaries-in-python/ He followed up with a performance comparison. https://gist.github.com/treyhunner/f35292e676efa0be1728 ** unpacking was nearly twice as fast as the 2nd place methods. (Bigger dict might change the ratio, but I expect ** unpacking to remain first.)
Trey's summary: "This is simple and Pythonic. There are quite a few symbols, but it’s fairly clear that the output is a dictionary at least." I consider the last point a major plus. User comment: "Beautiful. Pythonic. Thank you." No negatives. ---------- nosy: +terry.reedy _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36431> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
