It's in fact almost the same in Python.. :-)
import datetime
year = datetime.date.today().year
Of course, date doesn't have a time associated, so if you care about that too, you can do the same with a complete datetime object:
import datetime
year = datetime.datetime.today().year
(Obviously no different, but you can store datetime.datetime.today() in a variable before you grab the year, of course).
One key thing to note is that the time components can differ between 32-bit and 64-bit pythons in some python versions (2.5.x tree I think). So you will find things like hour/min/sec on some 64-bit platforms, while you get hour/minute/second on 32-bit.
