Why not use the timeit module instead ? > t1 = datetime.datetime.now() > for i in [str(x) for x in range(100)]: A bigger range (at least 10/100x more) would probably be better... > if int(i) == i: This will never be true, so next line... > i + 1 ...wont never be executed. > t2 = datetime.datetime.now() > print t2 - t1 > for i in [str(x) for x in range(100)]: > try: > int(i) +1 > except: > pass This will never raise, so the addition will always be executed (it never will be in the previous loop). > t3 = datetime.datetime.now() > print t3 - t2 BTW, you end up including the time spent printing t2 - t1 in the timing, and IO can be (very) costly. (snip meaningless results) The "test-before vs try-expect strategy" is almost a FAQ, and the usual answer is that it depends on the hit/misses ratio. If the (expected) ratio is high, try-except is better. If it's low, test-before is better. HTH -- http://mail.python.org/mailman/listinfo/python-list
