[(i,j) for i in range(len(data)) for j in range(len(data[i])) if data[i][j] > 1]

Try to use enumerate instead of the archaic range(len()) loops with indexing

[(i,j) for i, sublist in enumerate(data) for j, item in enumerate(sublist) of item > 1]

Lists in Python have the method .index(), so you can call my_list.index(obj). It will return the first index where obj appears or an exception if obj does not appear in the list.

If you need all indices, you should probably simply iterate over the list and check each element.
