Is it possible to index nested lists using tuples in python?

I just started with python and very soon wondered if indexing a nested list with a tuple was possible. Something like: elements[(1,1)]

One example where I wanted to do that was something similar to the code below in which I save some positions of the matrix that I will later need to access in a tuple called index.

index = ( (0,0), (0,2), (2,0), (2,2) )

elements = [ [ 'a', 'b', 'c'],
             [ 'c', 'd', 'e'],
             [ 'f', 'g', 'h'] ]

for i in index:
    print (elements [ i[0] ] [ i[1] ])

    # I would like to do this:
    # print(elements[i])

It seems like a useful feature. Is there any way of doing it? Or perhaps a simple alternative?

Answer

Yes, you can do that. I wrote a similar example:

index = [ [0,0], [0,2], [2,0], [2,2] ]

elements = [ [ 'a', 'b', 'c'],
             [ 'c', 'd', 'e'],
             [ 'f', 'g', 'h'] ]

for i,j in index:
    print (elements [ i ] [ j ])

a c f h
