Guido van Rossum added the comment: Hm, you seem to be right. Changing the bug title.
So, can we speed up method lookup? It's a shame that I have to start promoting this ugly idiom. There's a similar issue where s[:5]=='abcde' is faster than s.startswith('abcde'): ./python.exe -m timeit -s "a = 'hundred'" "a.startswith('foo')" 1000000 loops, best of 3: 0.281 usec per loop ./python.exe -m timeit -s "a = 'hundred'" "a[:3] == 'foo'" 10000000 loops, best of 3: 0.158 usec per loop ---------- title: string replace is too slow -> string method lookup is too slow _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17170> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
