时钟的滴答声不能与倒计时同时工作

我用的是特金特和温森。 我希望声音和倒计时同时工作。 现在,一旦点击声音超过计时器就会出现。

我看过一些倒数计时器的例子,使用“after”。例:自我。之后(1000,自我。倒计时)。但我同时需要两者。

import tkinter as tk

class NBack:

    def __init__(self, master):
        ##Title of the window
        self.master = master
        master.title("N-Back")


        ##It measures the screen size (width x height + x + y)
        ##The opened window will be based on the screen size
        master.geometry("{0}x{1}-0+0".format(master.winfo_screenwidth(), master.winfo_screenheight()))
        self.canvas = tk.Canvas(master, width=master.winfo_screenwidth(), height=master.winfo_screenheight(), \
                            borderwidth=0, highlightthickness=0, bg="grey")


        self.canvasWidth = master.winfo_screenwidth()
        self.canvasHeight =  master.winfo_screenheight()


        ##If removed, a white screen appears
        self.canvas.grid()


        """

        BREAK TIMER

        """


        self.play()

        self.canvas.create_text(((self.canvasWidth/2), (self.canvasHeight/2)-130), text="LET'S TAKE A BREAK!", font=(None, 90))
        self.display = tk.Label(master, textvariable="")
        self.display.config(foreground="red", background = "grey", font=(None, 70), text= "00:00")
        self.display.grid(row=0, column=0, columnspan=2)


    def play(self):
        return PlaySound('clock_ticking.wav', SND_FILENAME)


root = Tk()
my_gui = NBack(root)
root.mainloop()
