暂停就是读出X，定位置label.place就行了，buttom后面加command参数指定运行哪个函数吧

tk好久没用了，感觉好像是顺序的问题，这个例子可能会帮到你

[Python] 纯文本查看 复制代码

# import tkinter
try:
    import tkinter as tk
except ImportError:
    import Tkinter as tk

class Timer:
    def __init__(self, parent):
        # variable storing time
        self.seconds = 0
        # label displaying time
        self.label = tk.Label(parent, text="0 s", font="Arial 30", width=10)
        self.label.pack()
        # start the timer
        self.label.after(1000, self.refresh_label)

    def refresh_label(self):
        """ refresh the content of the label every second """
        # increment the time
        self.seconds += 1
        # display the new time
        self.label.configure(text="%i s" % self.seconds)
        # request tkinter to call self.refresh after 1s (the delay is given in ms)
        self.label.after(1000, self.refresh_label)

if __name__ == "__main__":
    root = tk.Tk()
    timer = Timer(root)
    root.mainloop()
