Heck you don't even need the magic number 12 in there.
import datetime
months = 'Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec'.split()
def last_months(n):
month = datetime.date.today().month
return [months[(month - i - 1) % len(months)
for i in range(n)]
In general I try to avoid magic numbers: always be explicit about the
semantic purpose of the number, either by binding a meaningful name to
it and only using that reference thereafter, or showing how that value
is derived.
