What did you expect to happen here?
alist[1][2] is the same as (alist[1])[2]; in other words, it is the 
third item in the second item in alist. The second item (alist[1]) is 
the integer 3 which is not subscriptable; if you try 3[2] at the 
interactive prompt you will get the same error.

If you are trying to get the elements of bList out of aList you should 
try alist[2][0], alist[2][1] etc.
