Question

I’m using a dictionary in python to make what is basically an infinite 2d array by using a tuple as the key

grid = {}
grid[(0,0)] = cell()

the value ‘cell’ is a new object. Can I have, say, a function within that object that is able to get its key value? ie. (0,0)

I could just put that data in the object itself but then I’d have it existing twice which seems like bad programming. Thanks!

Answer 1

class cell(object):
     def my_idx(self,grid):
         return grid.keys()[grid.values().index(self)]

then call it

some_cell.my_idx(grid)
