Python is an Object-Oriented Programming Language. That means that Python implements a programming paradigm based on “objects,” where every “object” can store some data and the code to modify it. Class is a description of the “object” that defines attributes that characterize the object and the methods that this object implements.

That means that Python implements a programming paradigm based on “objects,” where every “object” can store some data and the code to modify it. Class is a description of the “object” that defines attributes that characterize the object and the methods that this object implements.A class is a code template for creating objects. Objects have member variables and have behaviour associated with them. In python a class is created by the keyword class. An object is created using the constructor of the class. This object will then be called the instance of the class. In Python we create instances in the following manner.Overloading not supported: Unlike other object-oriented languages, Python does not support method overloading. This means that you cannot have multiple constructors with different parameters in a single class.

In-built Python classes are the most common data types in Python, such as strings, lists, dictionaries, and so on.

An object is any entity that has attributes and behaviors. For example, a parrot is an object. It has. Similarly, a class is a blueprint for that object.Classes are just a blueprint for any object and they cannot be used in a program. To create the object defined by the class, we use the constructor of the class to instantiate the object. Due to this, an object is also called an instance of a class. The constructor of a class is a special method defined using the keyword __init__ ().Natural language processing (NLP) is a field that focuses on making natural human language usable by computer programs.NLTK, or Natural Language Toolkit, is a Python package that you can use for NLP..
