abstract class in python 3 code example

Example 1: abstract method python

from abc import ABC, abstractmethod
 
class AbstractClassExample(ABC):
 
	def __init__(self, value):
        self.value = value
        super().__init__()
    
    @abstractmethod
    def do_something(self):
        pass

Example 2: python abstract class

# Python program showing 
# abstract base class work 
  
from abc import ABC, abstractmethod 
class Animal(ABC): 
  
    def move(self): 
        pass
  
class Human(Animal): 
  
    def move(self): 
        print("I can walk and run") 
  
class Snake(Animal): 
  
    def move(self): 
        print("I can crawl") 
  
class Dog(Animal): 
  
    def move(self): 
        print("I can bark") 
  
class Lion(Animal): 
  
    def move(self): 
        print("I can roar") 
          
# Driver code 
R = Human() 
R.move() 
  
K = Snake() 
K.move() 
  
R = Dog() 
R.move() 
  
K = Lion() 
K.move() 

Output:

I can walk and run
I can crawl
I can bark
I can roar
