title: Why is Label object not callable appearing
body: <p>I am in the process of making an OOP Countdown GUI with the letters, numbers and conundrum games.
  This is a snippet of my code so far.</p>
  <pre><code>  class App(tk.Tk):
      def __init__(self):
        super().__init__()
        self.title(&quot;Main&quot;)
        self.configure(bg=LIGHT_BLUE)
        self.title=tk.Label(master=self,bg=LIGHT_BLUE,font=(&quot;Arial&quot;,12,&quot;bold&quot;),text=&quot;!Countdown Games!&quot;,pady=5,padx=5)
        self.title.pack()
        self.frame=tk.Frame(master=self,bg=LIGHT_BLUE)
        self.LettersButton=tk.Button(master=self.frame,bg=LIGHT_BLUE,font=(&quot;Arial&quot;,12,&quot;bold&quot;),text=&quot;Letters&quot;,command=self.start_letters)
        self.LettersButton.grid(row=0,column=0,sticky=&quot;NESW&quot;,pady=10,padx=2)
        self.NumbersButton=tk.Button(master=self.frame,bg=LIGHT_BLUE,font=(&quot;Arial&quot;,12,&quot;bold&quot;),text=&quot;Numbers&quot;,command=self.start_numbers)
        self.NumbersButton.grid(row=0,column=1,sticky=&quot;NESW&quot;,pady=10,padx=2)
        self.LettersButton=tk.Button(master=self.frame,bg=LIGHT_BLUE,font=(&quot;Arial&quot;,12,&quot;bold&quot;),text=&quot;Conundrum&quot;,command=self.start_conundrum)
        self.LettersButton.grid(row=0,column=2,sticky=&quot;NESW&quot;,pady=10,padx=2)

    class Conundrum(tk.Toplevel):
      def __init__(self):
        super().__init__()

        self.title(&quot;Conundrum&quot;)
        self.frameA=tk.Frame(master=self,bg=LIGHT_BLUE)
        self.letterList=[]
        self.answer=r.choice(ninewords)
        self.anagram=anagram(self.answer)
        for x in range(9):
          self.letterList.append(ConundrumDisplay(self.frameA,x))
        self.frameA.pack()
        self.frameB=tk.Frame(master=self,bg=LIGHT_BLUE)
        self.letterEntryList=[]
        for y in range(9):

        self.mainloop()
        m.showinfo(&quot;Startgame&quot;,&quot;The game will start when you press OK&quot;)
        for x in range(9):
          self.letterlist[x].add_letter(x,self.anagram)
        self.bind(&quot;&lt;Key&gt;&quot;,self.process_key)

        self.bind(&quot;BackSpace&quot;,self.process_back)

  <p>The upper bit of code is a method from an App class which inherits from tk.Tk
  The error is in the super()._ _ init _ _() line in the conundrum class after you press the Conundrum button in the main wn
  This conundrum class is obviously the bit of code just below which inherits from tk.Toplevel.
  I have used tk.Toplevel before but it hasn't shown the error before.
  I have tried to reduce the amount of code that I am posting but if any more of it is necessary to figure out the error, then I can amend the question.</p>
