$ ./python -m timeit -s "a = 'hundred'" "a.find('x')" 1000000 loops, best of 3: 0.206 usec per loop $ ./python -m timeit -s "a = 'hundred'; f=a.find" "f('x')" 10000000 loops, best of 3: 0.176 usec per loop $ ./python -m timeit -s "a = 'hundred'" "'x' in a" 10000000 loops, best of 3: 0.0431 usec per loop ---------- _______________________________________ 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
