Python Abstract Classes to Learn Quickly

Here's the best example of how to understand the abstract classes of python quickly. An abstract class means it is a skeleton. You cannot instantiate abstract classes.

For Example:

The abstract class name is 'dog'

o = dog()

It gives an error. Since the 'dog' is an abstract class.

I am sharing with you a clear understanding of abstract class. So that you can tell confidently about these classes.

The syntax for Abstract Class

from abc, import ABC, abstractmethod 

class <class name>(ABC):

@abstractmethod 

def <method name>(): 

#abstract class definition

Python Abstract Class Explanation

from abc import ABC, abstractmethod

class AbsBaseClass(ABC):

def __init__(self):

print("Abstract class")

@abstractmethod

def abMeth(self):

pass

def conMeth(self):

print("I'm a concrete method")

class Derived(AbsBaseClass):

def abMeth(self):

print("I'm redefined")

o=Derived()

o.abMeth()

o.conMeth()
