b1 = Button(app, text = "correct!", width = 10,
            command = play_correct)
b1.pack(side ='left', padx = 10, pady = 10)
b2 = Button(app, text = "wrong!", width = 10,
            command = play_wrong)
b2.pack(side ='right', padx = 10, pady = 10)

您需要定义一个回调并将其绑定到您的按钮

b1 = Button(app, text = "correct!", width = 10,
            command = play_correct)
b1.pack(side ='left', padx = 10, pady = 10)
b2 = Button(app, text = "wrong!", width = 10,
            command = play_wrong)
b2.pack(side ='right', padx = 10, pady = 10)

def play_correct():
    self.num_correct += 1

def play_wrong():
    self.num_wrong += 1

此外，您可以在外部绑定回调

b1 = Button(app, text = "correct!", width = 10,
            command = play_correct)
b1.pack(side ='left', padx = 10, pady = 10)
b2 = Button(app, text = "wrong!", width = 10,
            command = play_wrong)
b2.pack(side ='right', padx = 10, pady = 10)

def play_correct():
    self.num_correct += 1

def play_wrong():
    self.num_wrong += 1

b1.bind("<Button-1>", onCorrect)

b2.bind("<Button-1>", onNotCorrect)
