Classes and Objects in PYTHON (Object Oriented Programming)

Solving a problem by creating objects is one of the most popular approach in programming. This is called Object Oriented Programming






This concept is based on using reusable code but differently from functions.
It is based on DRY (Don't Repeat Yourself) Principle.

CLASS :-

A class is a blueprint for creating objects. It can described as a group of objects. Objects are the instances of a class. We will further define this in our upcoming code in this post.

Lets see a basic program for the class and objects to understand it properly.




From that simple code you learn the use of classes and object. Now we will see the other methods of using classes in more simpler and shorter ways :-





Hope you understood the above code. We had used f-string method to print the whole detail which is more simpler and shorter than the previous code. In this method, we don't have to write the print command so many times. So making it shorter to write and less time consuming.

Now, lets see another way which is more shorter and simpler than the above one. This is also more important than the previous two methods. So, get ready for a flight :-





So these were the simplified programs of OOPS in PYTHON. Hope you understood the topic. In the next post, we will learn about Linked List.

First Python Programme

  If you are here, then I think you are a python enthusiast. On this website, we upload daily posts on new and basic programme for beginners.  So let’s start with the first code i.e. Hello World programme. So first of all you you should know how to give print command in python. To print we write print(“Hello World”). What’s inside the small brackets will be printed. So the programme is : print("Hello World") Hello World So, as we can see above, when we implemented the print command, the thing between the small bracket is printed. So let’s see some other examples In this example, we will store an integer value in a variable. And then print the integer will the help,of that variable. So let’s get started a = 3 print(a) 3 Another example Now we will store a string into a variable and then print the string with the help of that variable #if we put hastag in front of any line in python. Then there is no effect. #for storing the string in a variable, we have to enclose the whole s...

Doubly Linked List in PYTHON

  Here is the Python code for the Doubly Linked List :- #first of all creat a class node class Node :     def __init__ ( self , data ):         self . data = data         self . next = None         self . prev = None #now create a class of doubly linked list class DLL :     def __init__ ( self ):         self . head = None #function to insert the node at begining     def insertatbeg ( self , data ):         newnode = Node ( data )         newnode . prev = None         newnode . next = self . head         self . head = newnode #function to insert the node at the end     def insertatend ( self , data ):         newnode = Node ( data )         if self . head is None :             self . head ...

Queues in PYTHON

  The Python Code for Queue is here :- class Node: def __init__(self, data): self.data = data self.next = None class Queue: def __init__(self): self.front = self.rear = None def enqueue(self, data): newnode = Node(data) newnode.next = self.rear self.rear = newnode if self.front is None: self.front = newnode def dequeue(self): temp = self.rear while temp.next is not self.front: temp = temp.next self.front = temp temp.next = None def traverse(self): temp = self.rear while temp is not None: print(temp.data, end = " --> ") temp = temp.next print("None") new = Queue() new.enqueue(4) new.enqueue(1) new.enqueue(0) new.enqueue(2) new.traverse() new.dequeue() new.traverse() new.dequeue() new.traverse() 2 --> 0 --> 1 --> 4 --> None 2 --> 0 --> 1 --> None 2 ...
