How to get indices of a two dimensional list

[sramaswamy at gmail.com]

I have a list

x = [0] * 2
x = x * [2]
x[1,1] = 7

This gives me the x value
[[0,0] [0,0] [0,0] [0,7]]

I want to get the indices of the value 7.
i.e. something like
i = a.index(max(a)) gives me '1'

This only gives me the index in one dimension. Is there any method by
which  I can get (1,1) as the answer.

Thanks in advance.
