I did a year of Python. There are good and bad things with everything. Python was OK, the learning curve the first few weeks/months is really well planned.

I prefer Perl given a competent team. Mostly because of the CPAN Testers and because it is fun.

Bad with Python are details like e.g. no real one-liners. I also think there is something rotten with the language culture that e.g. results in lots and lots of language war trolls from 19-karma accounts on HN...
