Splitting lists?

[woodwardo]

I have this list:

   people = [ ("JT", 150), ("TJ", 80), ("TT", 120), ("BT", 170), ("Mike", 12), \
              ("AF", 27), ("Lea", 78), ("Leo", 180), ("Al", 55), ("GK", 110),  \
              ("JR", 111), ("VB", 76) ]

I'm trying to add the five lowest integers (12, 27, 55, 76, 78) together, but I don't know how to divide the integers from the strings...can I split them?

>>> numbers = [item[1] for item in people]
>>> numbers.sort()
>>> sum(numbers[:5])
248
>>>
