Python Super Tutorial 2

super() 

• will allow us not to call explicitly
• Enable multiple inheritance

class Computer():

    def __init__(self, computer, ram, storage):

        self.computer = computer

        self.ram = ram

        self.storage = storage

# Class Mobile inherits Computer

class Mobile(Computer):

    def __init__(self, computer, ram, storage, model):

        super().__init__(computer, ram, storage)

        self.model = model

Apple = Mobile('Apple', 2, 64, 'iPhone X')

print('The mobile is:', Apple.computer)

print('The RAM is:', Apple.ram)

print('The storage is:', Apple.storage)

print('The model is:', Apple.model)

Python Inheritance Detail

#Multiple inheritance
class Base1:
    @classmethod
    def f1(self):
    print  'Base1 f1'
    def f2(self):
    print  'Base1 f2'   

class Base2:
    def f1(self):
    print  'Base2 f1'
    def f2(self):
    print  'Base2 f2'
    def f3(self):
    print  'Base2 f3'   

class MultiDerived(Base1, Base2):
    def f1(self):
    print  'MultiDerived f1'

print '###########Multiple inheritance'
md = MultiDerived()
md.f1()  #MultiDerived f1
md.f2()  #Base1 f2
md.f3()  #Base2 f3
Base1.f1()  #Base1 f1  #classmethod
#Base2.f1()  #fail
#MultiDerived.f1()  #fail


#Multi-level inheritance
class Base:
    def f1(self):
    print  'Base f1'

class Derived1(Base):
    def f1(self):
    print  'Derived1 f1'
    def f2(self):
    print  'Derived1 f2'

class Derived2(Derived1):
    pass

print '###########Multi-level inheritance'
d2 = Derived2()
d2.f1() #Derived1 f1
d2.f2() #Derived1 f2      

Inheritance in Python

Lets discuss about Inheritance in Python using an example... Lets take a ride...

Here we consider Vehicle as Parent Class where as Car & Truck are sub-classes which inherit from the Parent class(Vehicle).

class Vehicle:
    '''Represents any Vehicle.'''
    def __init__(self, name, model):
        self.name = name
        self.model = model
        print('Initialized Vehicle: %s' % self.name)
    
    def details(self):
        '''Call my details.'''
        print('Name:"%s" model:"%s"' % (self.name, self.model))

class Car(Vehicle):
    '''Represents a Car.'''
    def __init__(self, name, model, price):
        Vehicle.__init__(self, name, model)
        self.price = price
        print('Initialized Car: %s' % self.name)

    def details(self):
        Vehicle.details(self)
        print('price: "%d"' % self.price)

class Truck(Vehicle):
    '''Represents a Truck.'''
    def __init__(self, name, model, price):
        Vehicle.__init__(self, name, model)
        self.price = price
        print('Initialized Truck: %s' % self.name)
    
    def details(self):
        Vehicle.details(self)
        print('price: "%d"' % self.price)

c = Car('Cooper', 100, 30000)
t = Truck('Jeep', 200, 50000)

print() # prints a blank line

vehicles = [c, t]
for member in vehicles:
    print() # prints a blank line
    member.details() # works for both Cars and Trucks
