Benchmarks are worthless. By that I mean they have no value to me. What matters is the performance on real problems, such as generating the 1st 6th Generation Type [1,2] Mersenne Hailstone Collatz sequence. That's a BIG number and needs BIG arithmetic to solve. Java has a BigInteger module and can solve it in less than 10 minutes: C:\Python23\user\pyjava>java Collatz 2 177149 1 Processing time: 571690 x/2 iterations: 1531812 3x+1 iterations: 854697 The arguments evaluate to 2**177149-1. And because this is a Mersenne number, the sequence diverges until it's over 280000 bits before converging to 1 bit after 2386509 iterations. But is 571 seconds a reasonable amount of time for such a difficult problem? Compare it to Python with the GMPY module: C:\Python23\user\pyjava>collatz.py 2 177149 1 r1 1531812 r2 854697 in 72.9869999886 seconds Yes, it would appear that in this real world application Java is ridiculously slow. Of course, Python is doing the heavy lifting with GMPY which is a compiled C program with a Python wrapper. But so what? Maybe the reason I use Python is BECAUSE the math module is compiled C. Duh. With Python/GMPY I get the high level power I need for the algorithms without sacrificing the low level muscle I need for the heavy arithmetic. > > >Take a look at PyGame. > > on my way :) > > best > k -- http://mail.python.org/mailman/listinfo/python-list
