Python OOP’s Concept
Python oop’s concept of Object-oriented programming is a programming platform that uses objects and a class of programming concepts. The aim is to implement real-world concepts like inheritance, polymorphisms, encapsulation, etc. in the programming. With our Python training in Pune, you’ll gain the knowledge and confidence to use Python effectively in your work. You’ll be equipped with the skills needed to write efficient and scalable Python code, work with data, and develop applications. And with our job placement assistance, you’ll have access to job opportunities in Pune’s booming tech industry. The main motto or goal behind the concept is to bind data and functions along with them which will work together as a single unit so that we don’t have access to work on it.

Class
Objects
Polymorphism
Encapsulation
Inheritance
Let’s elaborate these concepts one by one :

It can be defined as a collection of objects where all data is stored in one platform.
Because it contains a blueprint or the prototype from where an object can be created va this platform.
Syntax :
Class class_name:
#statement 1

We we need to define an object it can be as it will decide the state or behavior of the entity.
The entity means what it is a real-world object like a table, chair mouse, speaker, and many more so these things are called as objects.
If you’re looking to expand your skill set and enhance your career prospects, then learning Python is an excellent choice. Python is a powerful and versatile programming language used by developers, data scientists, and artificial intelligence specialists worldwide. And with the increasing demand for Python skills, now is the perfect time to invest in a Python course in Pune.
Syntax :
Obj1=java()
Example :
Class java :
A1=”system”
Def __init__(self,name1):
Self.name1=name1
Window = java(“window”)
Linux = java(“linux”)
Print (“window is a {}”.format(window.__class__.a1))
Print (“linux is a {}”.format(linux.__class__.a1))
Print(“my system is {}”.format(window.name))
Print(“my system is {}”.format(linux.name))

It is a concept where from one class you can take or inherit property from another class. So this process of transferring methods or functions is called as inheritance.
So here we will learn about the concept like
Base class (parent class or super class)
Derived class (child class or sub-class)
Syntax
Class pqr :
Def a():
–
Class xyz :
Pqr.__init__()
Def a()
For example :
Class abc :
Def __init__(self,x,y):
Self.x=x
Self.y=y
Def info(self):
Print(“the value of x is”,x)
Print(“the value of y is”,y)
Class lmn :
Def __init__(self,x,y,z,p)
Self.z=z
Self.p=p
To invoke the property from abc class write following code Abc.__init__(self,x,y)
Def info(self):
Print(“value for x is”,x)
Print(“value for y is”,y)
Print(“value for z is”,z)
O=lmn(12,23,34)
Call the object
o.info()
so you will get output like
value for x is 12
value for y is 23
value for z is 34

what is __init__
this method works like a constructor it means we can import all methods from the class so we create his instance with the help of the constructor.
what is self
in our class methods, it must contain one extra parameter which is indicated by self.
