クロックがTkinterでdefを使用しようとしていません

Question

スレッドを使用してループを作る方法を尋ねる別の質問があります： Threads And Time + Tkinter In Python しかし、ループのようには機能しません。それはクロックをうまくロードしますが、更新されません。

import tkinter as tk

class FirstFrame(tk.Frame): 
    trys = 3

      self.number.config(text=self.trys) 
      self.trysremain.config(text="Trys remaining") 
      if self.trys == 0: 
       root.destroy()

    app.password = password2.read() 
    password2.close() 
    root.mainloop() 

Answer 1

は、だから私はいくつかの助けを持って、私は言うビットでそれを見つけることができた：

def update(self, event=None): 
    timecall = datetime.datetime.now() 
    self.clock.config(text=self.timecall) 
    self.after(1000, self.update) 

私がしなければならなかったすべてがhttps://stackoverflow.com/users/1222951/rawing

に self.clock.config(text=self.timecall)

self.clock.config(text=timecall)の功績を変更しました
