Agreed. I used to do my major numeric calculations in OS/2 REXX, which served me quite well in the 1990s. But Python smokes it, even the oh-so-slow Python 3 where every integer is a bignum (which is fair comparison against REXX, where every number is... uhh... a string). A modern, optimized language, even one that's perceived as "slow", is able to do many orders of magnitude more calculations per second than a human can.... okay, that's hardly fair, but it's about the only absolute we're ever going to get :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
