def clearBoard(self):
for row, col in self.label.keys():
self.board[row][col] = Empty
self.label[(row, col)].config(text=' ')Similarly, picking a move, at least in random mode, is simply a matter of picking a
nonempty slot in the board array and storing the machine’s mark there and in the GUI
(degree is the board’s size):
def machineMove(self):
row, col = self.pickMove()
self.board[row][col] = self.machineMark
self.label[(row, col)].config(text=self.machineMark)def pickMove(self):
empties = []
for row in self.degree:
for col in self.degree:
if self.board[row][col] == Empty:
empties.append((row, col))
return random.choice(empties)Finally, checking for an end-of-game state boils down to inspecting rows, columns, and
diagonals in the two-dimensional list-of-lists board in this scheme:
