I wasn't previously familiar with the 3GL / 4GL nomenclature, but
based upon the definitions given at Wikipedia, Python is clearly a
3GL.  That said, virtually all general-purpose languages in common
usage today would be 3GLs, so the distinction does not seem terribly
useful to me.  The terms "4GL" and "5GL" while suggesting a language
that is somehow more "advanced" than a 3GL, seem to be mainly 80s
hype.
