I'm still not sure exactly what you want to achieve...

You're starting with a list of lists of integers, correct?  Are the
interior lists all the same length?

Do you want to produce a new list which contains the average of all
the sublists?  In this case, you can do that using the sum() and len()
functions -- check Ben's reply.  A list comprehension would work well
here (see the tutorial on python.org for information on list
comprehensions).

Is there anything else you want to do?
