Question

我正在做一个记忆游戏，我不知道如何跟踪是否已单击一个按钮。如果两个图像在单击时不匹配，我希望这些图块更改回默认图像，但如果它们匹配则保留为新图像。

                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1                 
                    img1.grid(row=0, column=2)  



                if master == 4:
                    load1 = Image.open('Kittens1.GIF')
                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1                 
                    img1.grid(row=1, column=0)  



                if master == 5:
                    load1 = Image.open('Kittens2.GIF')
                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1                 
                    img1.grid(row=1, column=1)  


                if master == 6:
                    load1 = Image.open('Kittens3.GIF')
                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1                 
                    img1.grid(row=1, column=2)

#skapar fönstret
root=Tk()  
start_time = time.time()

#root blir master 
mem=MemoryBricks(root)

root.mainloop()


elapsed_time = time.time() - start_time

print("Your time is", elapsed_time)

我认为我可能必须创建一个新类或一个函数。还是有人对如何轻松实现此操作有任何建议？

您可以有一个辅助变量，该变量将充当标志。

例如将其定义为self.flag = False。单击按钮时，以True（self.flag = True）更改变量的值，这是跟踪按钮是否被按下的方法

例如，您要跟踪是否单击了button1：

 class MemoryBricks:
      def __init__(self, master):
           # Define "flag variable" for button1
           self.flag_btn1 = False

在单击button1时将执行的功能（或代码的一部分）中，更改标志的状态：

 class showImage(MemoryBricks):
      def __init__(self, master):
           if master == 1:
                # Change state of the flag
                self.flag_btn1 = True
                load1 = Image.open('Kittens1.GIF')
                load1Size = load1.resize((145, 145))
                render1 = ImageTk.PhotoImage(load1Size)
                img1 = Label(image=render1)
                img1.image = render1
                img1.grid(row=0, column=0)

现在您可以检查是否单击了button1：

例如，在某些信号/动作上：

 if self.flag_btn1: # True
      print("button1 was clicked")
 else: # False
      print("button1 wasn't clicked")
