Ok, that was mean-spirited.  The code is below - it's related to
another problem but maybe it can be adapted to your own. Good luck!

def irows(n):
    i=0
    while True:
        yield divmod(i,n)
        i += 1

x = [0,0,0,7,0,0,0,0]

d = dict(zip(enumerate(x), irows(2)))

assert d[x.index(7),7] == (1,1)
assert d[x.index(0),0] == (0,0)

d = dict(zip(irows(2),x))

assert d[1,1] == 7

sudoku = dict(zip(irows(9),[[0]]*81))
