Assume that the class Vehicle in Q.1 is already written in Python. Write code in Python with using inheritance for implementation of 02 child classes Car(NumberOfSeats) and MotorBike(SeatSize). In main code, create 05 objects of both Car and MotorBike classes, input their data, and serialize these objects to a binary file "Vehicles.bin". Read data from ..

I’ve overloaded __init__ constructor method with different parameters and also make use of multiple inheritance here. This code was executed in Python 3.x. You can try and have review over it. Thanks! class Author: def __init__(self): self.auth_name="" self.auth_city="" def __init__(self,a,c): self.auth_name=a self.auth_city=c def showAuth(self): print(self.auth_name,self.auth_city) class Publisher: def __init__(self): self.pub_name="" self.pub_city="" def __init__(self,p,c): self.pub_name=p self.pub_city=c ..

I’ve been experimenting and trying to find answers, but still don’t understand why I can access some args that were not passed to the child class and some not. Given this code: class Signals(object): def __init__(self, numbers): super().__init__() self.numbers = numbers self.factor = 2 def get_calculations(self): self.beau = Beau(self.numbers) self.beau.calculation() self.jolais = Jolais() self.jolais.calculation() print("self.beau.value", ..
