TypeError : encode() missing 1 required positional argument: 'iterations'

Question

i dont know what is triggering this error. i dont know why i keep getting this error . i already change a few parts of code and still i get this error . i have been trying to fix it for 2 days .

Traceback:

        h.save()
        return "%s$%d$%s$%s" %(self.algorithm, iterations, salt, hashes[0])

can someone explain why i keep getting this error please ? i have spend hours searching all the related questions here and nothing solves it .

Answer 1

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