Python __init__ Issue: Unbound Method __init__() Must Be Called With Bank Instance As First Argument (got Int Instance Instead)

class Teller(object): def __init__(self): self.occupied = False self.timeLeft = 0 self.totTime def occupy(self, timeOcc): self.occupied = T

   def __init__(self, numTellers, hoursOpen):
