python will in any case be somewhere in PATH, just not so
reliably in /usr/bin.  (In fact, I have never in 7 or 8
years of using Python seen it in /usr/bin.)  env does find
it in PATH, so you don't need to move python around to
accommodate scripts.  (Unfortunately, env isn't always
in the same place either!  but it's better than python.)
/usr/bin/env in the first line is standard.
