Wow! Thanks for all of the great additional feedback and responses
since I last checked in. The help this group provides is amazing.
I'm glad I found it.
@Andrew -- Thanks for the clarification on the nested for loop and how
to intrepret it. Also, thanks for the information on generators. I

Use extend instead of append:
* Append -> add the one item to the end of the list
* Extend -> add the list of items to the end of the list

Just to throw my hat in the ring, this is another way you can do this:
[(lambda x : [int(ii) for ii in x])(y) for y in a]
However, I do think dusans way is more elegant.

About speed, and memory consumption:
List comprehensions
(http://docs.python.org/tut/node7.html#SECTION00714) are
just shortcuts for for-loops.
