Its well known that Python 3 is generally slower than Python 2. Cecil's claim shouldn't be controversial, any more than Python is generally about 10 to 100 times slower than C should be controversial. But for what it's worth: [steve@ando ~]$ python2.7 -m timeit i=1; L=sorted([30,20,50,10,40]); L[i+1] 100 loops, best of 3: 1.54 usec per loop [steve@ando ~]$ python3.3 -m timeit i=1; L=sorted([30,20,50,10,40]); L[i+1] 100 loops, best of 3: 1.62 usec per loop which is an 8% slowdown. On the other hand: [steve@ando ~]$ python2.7 -m timeit i='1'; L=sorted([30,20,50,10,40]); L[int(i)+1] 10 loops, best of 3: 2.6 usec per loop [steve@ando ~]$ python3.3 -m timeit i='1'; L=sorted([30,20,50,10,40]); L[int(i)+1] 10 loops, best of 3: 2.29 usec per loop which is a 12% speed up. So the lesson is, micro-benchmarks are not a good guide to whole-application benchmarks. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
