Python Tkinter线程

Question

我需要一个使用tkinter的程序的帮助。所以我尝试用一​​个按钮循环播放一些图片，但是有两个循环，当我按下一个按钮或者消失或者返回到第一个按钮（这很难解释）。我在问自己，如果我可以在这里使用一些线程，并且我需要帮助，因为我以前从未使用它。

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() 
     square3 = Image.open("Square3.jpg") 
     square3r = ImageTk.PhotoImage(square3) 
     self.square3img = Label(self.windowSq, image=square3r) 
     self.square3img.image = square3r 
     self.square3img.place(x=30, y=100) 

    elif self.num == 3: 

     self.square3img.destroy() 
     square4 = Image.open("Square4.jpg") 
     square4r = ImageTk.PhotoImage(square4) 
     self.square4img = Label(self.windowSq, image=square4r) 
     self.square4img.image = square4r 
     self.square4img.place(x=30, y=100) 

    elif self.num == 4: 

     self.square4img.destroy() 
     square5 = Image.open("Square5.jpg") 
     square5r = ImageTk.PhotoImage(square5) 
     self.square5img = Label(self.windowSq, image=square5r) 
     self.square5img.image = square5r 
     self.square5img.place(x=30, y=100) 

    elif self.num == 5: 
     self.square5img.destroy() 
     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) 
     self.num = 0 
     self.windowSq.after(50000, self.next) 

def next1(self): 

    self.num1 = self.num1 + 1 

    if self.num1 == 1: 

     self.square1img.destroy() 
     square2 = Image.open("Square2a.jpg") 
     square2r = ImageTk.PhotoImage(square2) 
     self.square2img = Label(self.windowSq, image=square2r) 
     self.square2img.image = square2r 
     self.square2img.place(x=435, y=100) 

    elif self.num1 == 2: 

     self.square2img.destroy() 
     square3 = Image.open("Square3a.jpg") 
     square3r = ImageTk.PhotoImage(square3) 
     self.square3img = Label(self.windowSq, image=square3r) 
     self.square3img.image = square3r 
     self.square3img.place(x=435, y=100) 

    elif self.num1 == 3: 

     self.square3img.destroy() 
     square4 = Image.open("Square4a.jpg") 
     square4r = ImageTk.PhotoImage(square4) 
     self.square4img = Label(self.windowSq, image=square4r) 
     self.square4img.image = square4r 
     self.square4img.place(x=435, y=100) 

    elif self.num1 == 4: 

     self.square4img.destroy() 
     square5 = Image.open("Square5a.jpg") 
     square5r = ImageTk.PhotoImage(square5) 
     self.square5img = Label(self.windowSq, image=square5r) 
     self.square5img.image = square5r 
     self.square5img.place(x=435, y=100) 

    elif self.num1 == 5: 
     self.square5img.destroy() 
     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) 
     self.num1 = 0 
     self.windowSq.after(50000, self.next1) 

整个程序是在一个类（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")

你有很多冗余代码以上。这个想法是先将图像存储在一个列表中，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，以便在每个列表中保留您的位置，然后根据您需要的列表更改标签上的图像（我使用按钮，并注意只有一个按钮被创建 - 永远不会被破坏，并且每次只更改图像）。或者，您可以使用一个类和两个实例类，将不同的图像列表传递给每个实例。这只是一个简单的概念验证程序。点击按钮/图像进行更改。
