Python Inheritance

• Python supports all the four types of inheritance : Single, Multiple, Hierarchical and Multilevel
• If during multiple inheritance there are two classes that have the same method then from method from the class that is inherited first by the child will only be available
• Private attributes from the parent class cannot be accessed in the child class
• When an method in the parent class is redefined in the child class it is called as Method Overriding

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age
 
	def print_name(self):
		print(f"Person Name : {self.name}")
 
class Professor(Person):
    def isProfessor(self):
        return f"{self.name} is a Professor"
 
	def print_name(self):
		print(f"Professor Name : {self.name}")
 
if __name__ == '__main__':
	sir = Professor("John", 30)
	print(sir.isProfessor())

Accessing Base Class Constructor/ Methods

The constructor/ methods of the parent class can be accessed using the super() keyword

class Vechicle:
    def __init__(self, registeration_number) -> None:
        self.registeration_number = registeration_number
        print("Inside Vechicle Constructor")
 
    def vechile_type(self, company):
        print(f"Vechile type : {company}")
 
class Car(Vechicle):
    def __init__(self, registeration_number) -> None:
        super().__init__(registeration_number)
        print("Inside Car Constructor")
 
    def new_car_type(self, species, color):
        super().vechile_type(species)
        print(f"Color : {color}")
 
if __name__ == '__main__':
    c1 = Car("ABC123")
    c1.new_car_type("Audi", "Black")

When super() of an method/ property is called Python looks up the Class MRO (Method Resolution Order) and calls the method/ property that is next in the list
Helpful in understanding the order in which the method/ property will be called when using multiple inheritance
