__init __() 1 erforderlich Positions Argument fehlt: 'Controller'

Question

die folgende Fehlermeldung bekommen:

TypeError: __init__() missing 1 required positional argument: 'controller'. 

Ich kann irgendwie nicht scheinen, diese Arbeit zu bekommen. Wenn Sie weitere Informationen benötigen, hinterlassen Sie bitte einen Kommentar.

class SampleApp(tk.Tk):

     tk.Tk.__init__(self, *args, **kwargs)

     # on top of each other, then the one we want visible

Answer 1

Sie erklären App.__init__ zwei Argumente zu nehmen (master und controller), aber Sie eine nur liefern, wenn man es so nennen (app = App(root)). Sie müssen diesem Aufruf ein entsprechendes zweites Argument übergeben.

c = ??? 
app = App(root, c)
