For filter and map, list comprehensions and generator expressions are
the answer.
>>> numbers = [5, 9, 56, 34, 1, 24, 37, 89]
>>> [x for x in numbers if x < 30]
[5, 9, 1, 24]
>>> (x for x in numbers if x < 30)
>>> list(_)
[5, 9, 1, 24]

Hey folks,
I'm sitting over here in the AppleScript talk and Jacob is explaining a
module called 'appscript' that interfaces to the Apple Events system.
What caught my eye was this example:
from appscript import *
ab = app('Address Book')
people = ab.people.filter(its.emails != [])
