RecursionError: maximum recursion depth exceeded creating object of a class inside other class

Question

I want to call an object of another class in my class but when i run the code it says: RecursionError: maximum recursion depth exceeded

Any ideas of what error im making?

This is my code:

class Anden(Estacion):

    def __init__ (self,ID):

        self.ID=ID
        self.filas_anden=[0,0,0,0,0,0,0,0,0,0]
        self.puertas = []

        while len(self.puertas) < 10:
            puerta = Puerta(len(self.puertas))


    def asignar_fila(self, pasajero):
        aux=10000000000
        puerta_asignada = min(filas_anden)

        for i in range(10):            
            if aux > self.puertas[i].total_fila:
                aux = self.puertas[i].total_fila
                fila_asignada = i
        pasajero.fila_actual = i 
        self.filas_anden[i] +=1
        self.puertas[i].append(pasajero)


class Puerta(Anden):

    def _init_ (self,ID):
        self.ID = ID
        self.lista_pasajeros = []
        self.total_fila = 0


    def ingresa_pasajero_fila(self, pasajero):
        self.lista_pasajeros.append(pasajero)
        self.total_fila = self.total_fila + 1

    def remover_pasajero_fila(self, pasajero):
        self.lista_pasajeros.remove(pasajero)
        self.total_fila = self.total_fila - 1

The while loop condition will not change

So a few things. You made a typo in your Puerta constructor method. You're using _init_ instead of __init__, so when you initialize a Puerta object it's falling back to the constructor of its base class, Anden. That's what's causing this recursion error. Secondly, in your Anden constructor method, I think what you're trying to achieve is the following

def __init__ (self,ID):
    self.ID=ID
    self.filas_anden=[0,0,0,0,0,0,0,0,0,0]
    self.puertas = []

    while len(self.puertas) < 10:
        self.puertas.append(Puerta(len(self.puertas)))

In your current implementation, you're just setting an arbitrary variable puerta to a Puerta object which doesn't change the puertas list of your Anden instance and the while loop keeps going forever. Hope this helps!

You're having the same problem as Recursion error with class inheritance. A solution would be to make Puerta inherit from a base class common to Anden, instead of inheriting from Anden directly.
