我需要帮助使用tkinter的程序。所以我尝试使用一个按钮来循环播放一些图片，但是有两个循环，当我按下一个按钮要么消失要么回到第一个按钮（这有点难以解释）。我问自己是否可以在这里使用一些线程，我需要帮助，因为我以前从未使用过它。
这是代码的一部分：
square1 = Image.open("Square1.jpg")
square1r = ImageTk.PhotoImage(square1)
self.square1img = Label(self.windowSq, image=square1r)
self.square1img.image = square1r
self.square1img.place(x=30, y=100)
square1 = Image.open("Square1a.jpg")
square1r = ImageTk.PhotoImage(square1)
self.square1img = Label(self.windowSq, image=square1r)
self.square1img.image = square1r
self.square1img.place(x=435, y=100)
next = Button(self.windowSq, text="Next", font=self.customFont, relief=GROOVE, command=self.next, cursor='hand2')
next.place(x=185, y=380)
self.num = 0
next1 = Button(self.windowSq, text="Next", font=self.customFont, relief=GROOVE, command=self.next1, cursor='hand2')
next1.place(x=600, y=380)
self.num1 = 0
def next(self):
self.num = self.num + 1
if self.num == 1:
self.square1img.destroy()
square2 = Image.open("Square2.jpg")
square2r = ImageTk.PhotoImage(square2)
self.square2img = Label(self.windowSq, image=square2r)
self.square2img.image = square2r
self.square2img.place(x=30, y=100)
elif self.num == 2:
self.square2img.destroy()

整个课程都在课堂上（如果你想知道......）
class Window(Frame):
def __init__(self, master):
Frame.__init__(self, master)
self.master = master
self.master.resizable(0, 0)
master.title("Arcade Games")
master.geometry("800x600+560+240")

上面有很多冗余代码。我们的想法是首先将图像存储在列表中，然后在列表中循环。您可以使用2个按钮调用2个不同的功能（每个列表一个），2个图像列表和2个计数器，以保持每个列表中的位置，然后从您想要的任何列表中更改标签上的图像（我使用了按钮如下所示，并注意只创建一个按钮 - 永不销毁，每次只更改图像）。或者，您可以使用一个类和该类的2个实例，传递要加载到每个实例的不同图像列表。这只是一个简单的概念验证程序。单击按钮/图像进行更改。
