NameError: Name 'Radiobutton' ist nicht definiert

Question

Ich baue eine Messaging-Anwendung und Tkinter für GUI verwenden. Ich versuche, einige Tasten zu erstellen, aber ich erhalte eine Fehlermeldung:

Traceback (most recent call last): 

    File "/home/artur/Documents/MScProject/MSc Project/Task #179276/main_program.py", line 174, in <module> 
    app = Application(the_window) 

    File "/home/artur/Documents/MScProject/MSc Project/Task #179276/main_program.py", line 49, in __init__ 
    self.AES_radiobutton = Radiobutton(text = 'AES algorithm', bg = color, variable=self.var, value=0) 
NameError: name 'Radiobutton' is not defined

ich immer noch, obwohl die GUI sehen und ein Eingabefeld, aber viele Elemente fehlen. Was könnte das Problem hier sein?

Answer 1

Einfacher Import von Radiobutton-Modul löste das Problem
