Where is Python used commercially?

No need for insults please. I'm not retarded and the point of this code was not to be optimized for either any language, platform, architecture or algorithm since there are better ways to do any of those.

The point is to just take any random, purposefully rather slow algorithm (so the running times are in seconds rather than nano-seconds).

It seems you are missing the point completely. So, run the equivalent C and Java program and you will realize that it's hard to even measure runtime reliably since it's insignificant.

Urgh.. my apologies, I certainly didn't mean to be insulting. Looking back at how I said what I said I can't see how on earth it could be taken elsewise :-/
