If you're planning to do anything serious with a 2D array, you should 
probably look at numarray:
    http://www.stsci.edu/resources/software_hardware/numarray

>>> import numarray as na
>>> arr = na.array(range(10), shape=(5, 2))
>>> arr
array([[0, 1],
       [2, 3],
       [4, 5],
       [6, 7],
       [8, 9]])
>>> arr[0,1]
1
>>> arr[4,0]
8
If you're not doing any heavy computation, you can probably do this with 
nested lists:

>>> arr = [[0, 1],
...        [2, 3],
...        [4, 5],
...        [6, 7],
...        [8, 9]]
>>> arr[0][1]
1
>>> arr[4][0]
8
