super() in python

In python, super() is a simple way to solve inheritance issues. It has two major use:

allow to avoid using base class explicitly
working with multiple inheritance.

examples:

class Mammal(object):
  def __init__(self, mammalName):
    print(mammalName, 'is a warm-blooded animal.')
    
class Dog(Mammal):
  def __init__(self):
    print('Dog has four legs.')
    super().__init__('Dog')
    
d1 = Dog()

output:

Dog has four legs.
Dog is a warm-blooded animal.

class Animal:
  def __init__(self, animalName):
    print(animalName, 'is an animal.');

class Mammal(Animal):
  def __init__(self, mammalName):
    print(mammalName, 'is a warm-blooded animal.')
    super().__init__(mammalName)
    
class NonWingedMammal(Mammal):
  def __init__(self, NonWingedMammalName):
    print(NonWingedMammalName, "can't fly.")
    super().__init__(NonWingedMammalName)

class NonMarineMammal(Mammal):
  def __init__(self, NonMarineMammalName):
    print(NonMarineMammalName, "can't swim.")
    super().__init__(NonMarineMammalName)

class Dog(NonMarineMammal, NonWingedMammal):
  def __init__(self):
    print('Dog has 4 legs.');
    super().__init__('Dog')
    
d = Dog()
print('')
bat = NonMarineMammal('Bat')

output:

Dog has 4 legs.
Dog can't swim.
Dog can't fly.
Dog is a warm-blooded animal.
Dog is an animal.

Bat can't swim.
Bat is a warm-blooded animal.
Bat is an animal.

in order to see the sequence of inheritance, we can view __mro__ method

>>> Dog.__mro__
(<class 'Dog'>, 
<class 'NonMarineMammal'>, 
<class 'NonWingedMammal'>, 
<class 'Mammal'>, 
<class 'Animal'>, 
<class 'object'>)
