   For almost anything, it's good enough - or more than
   good enough. The large number of libs has left little
   beyond its (relatively easy) reach. It's also READABLE,
   nothing too mysterious about the syntax or defining/using
   vars and such.

   Do kinda pref "{ }" or "begin end" over the dangling
   depth thing ... get six or eight levels into something
   and it's a total bitch to spot what's inside what
   without using comments.

   However it's NOT as fast as the true compiled langs.
   Yea, yea, there's Python compilers - turn it into 'C' -
   but with sometimes difficult barriers and the final exe
   tends to be pretty fat - VERY VERY fat if you get past
   version issues by encapsulating all the needed libs
   inside the exe.

   In any case, it's become the "new BASIC" for good reasons
   and I don't see that being changed anytime soon. It's
   in *everything* now from microcontrollers on up.

   I never learned it until M$ started sneaking it into
   their OS junk. "What's a .py ???". The good side of
   that is that it was right near the v2 -> v3 transition
   and I decided to learn the 'new and improved'.

   Anyway, I do full apps and utils in Python and almost
   always use it to proto stuff before re-writing in 'C'
   or Pascal.
