I'm in my first AND LAST computer science class and I really need help with our final project. Up to this point all of my assignments have been completed from my teacher and TA standing over my shoulder telling me exactly what to do. I'm pretty sure they're just as frustrated with my inability to comprehend this program as I am. With the first part of the assignment I have about half of it done, but can't figure out 3 functions; isFull (to check if the board is full), winsFor (to determine if somebody has won horizontally or vertically), and hostGame (to host the game..? I think). Here is what I have thus far....help is greatly appreciated!

    with an arbitrary number of rows and cols

            boardRow = []
            for col in range( 7 ):
                boardRow += [' ']   # add a space to this row
            self.data += [boardRow] # add this row to the board
                # do not need to return inside a constructor!
