I think you're looking for something like the below. I'm not sure what you want to do with them when you access them though.

indexes = [(4,6), (0,2), (2,4), (8, 10)]
arr = [
    [ . . . . | | | . . . . . ],
    [ | | | . . . . . . . . . ],
    [ . . | | | . . . . . . . ],
    [ . . . . . . . . | | | . ]
]

for x in zip(indexes, arr):
    index = x[0]
    row = x[1]
    print row[index[0]:index[1]+1]
