STINNER Victor <vstin...@python.org> added the comment:
dict.get() is a method call wheras "key in dict" and "dict[key]" are operators. Method calls are still slower than operators, even after past optimizations. For example, when dict.get was converted to METH_FASTCALL, it was around 20 ns faster: https://vstinner.github.io/fastcall-microbenchmarks.html See also closed bpo-17170 "string method lookup is too slow". ---------- nosy: +serhiy.storchaka, vstinner _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38278> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
