After that long journey with Python, now I am totally into it. Absolutely amazing thing to know and learn.

But for analyzing data, basic Python isn't the only thing you should know. There are some of its libraries, which you should definitely give a try. 

So, what is a Library? In programming world, libraries are like collection of pre-written codes, written in any specific language(almost every programming language has their own set of libraries), written by developers, and are mostly used for software development purpose. 

Why do we need it? Well, it makes our life easy! As there are a lot of collection of codes, which we can use anytime we want to(in the right place), why not using those? It also makes out code much efficient and easy to execute.

So, what exactly are those libraries? Mostly there's 4 libraries which we use: Pandas, NumPy, Matplotlib, and Seaborn.

I learnt Pandas, Matplotlib and Seaborn from Kaggle, and the NumPy part from YouTube.
