Maybe this is more readable:
ar = [[3,3,3,3],
[3,3,3,1],
[3,3,4,3]]
print sorted( [(r,c) for r,row in enumerate(ar) for c in
xrange(len(row))],
key=lambda (r,c): ar[r][c]
)[0]
I don't know if operator.itemgetter can be used here, I think it's too
much complex.
With python 2.5 you can probably simplify it a little (and speed it up)
with something like:
print min( [ (r,c) for r,row in enumerate(ar) for c in xrange(len(row))
],
key=lambda (r,c): arr[r][c]
)
