A new version of Python (2.5) came out this week... I still have trouble with the importance of whitespace in Python, but there's no denying its continued growth and power. I do worry, as it adopts convenience grammars and features from other languages, that its gets a bit sprawl-y, but thus far, their PEP system keeps things in line.
And Python's got some nifty things going for it (check out Yahoo's Python center). In particular, I've a new found appreciation for their language evolution model of late.
Most of the time, (Perl 6 is a good counterpoint) classic CS design philosophy suggests if you're going to make changes, make them once (and complete), so that everyone can get over it and get on board. Enh.
Python's been more incremental - generally they break you just a *little* with each regular-ish rev, though some 5 revisions down the road it might not be so compatible. Basically, they create an incentive for people to stay on the upgrade chain.
