TypeError: encode() fehlt 1 benötigt positional Argument: 'Iterationen'

Question

Ich weiß nicht, was diesen Fehler auslöst. Ich weiß nicht, warum ich diesen Fehler bekomme. Ich ändere bereits ein paar Teile des Codes und immer noch bekomme ich diesen Fehler. Ich habe versucht, es für 2 Tage zu beheben.

Traceback:

     h.save()

kann jemand erklären, warum ich bitte immer diese Fehlermeldung zu halten? Ich habe Stunden damit verbracht, alle verwandten Fragen hier zu suchen, und nichts löst es.

Answer 1

def encode(self, password, salt, iterations=None): 
    if iterations is None: 
     iterations = self.iterations 
    # then ur code......
