Hello NLP learner!! I hope you had visited our last article – Introduction to Natural Language Processing using Python. With that, you would have got an idea that Natural Language Processing essentially deals with Text Analytics. As a next step, we naturally need to learn how to deal with text or in other words strings before we plunge into advanced techniques of NLP. This article will talk about useful string operations using Python for NLP beginners. Get ready for some facts about strings and interesting string operations.!!
