Today you'll learn about a very powerful library called Numpy. We'll learn about Numpy Array(np array for short) and operations on them, along with what makes them better than the pre-existing data structures. The most important entity in the whole NumPy package is the Numpy Array. If you've worked with Python before you must be familiar with the data structure called Lists. List are containers that can store any kind of data in it.

Numpy is a math library for python. It enables us to do computation efficiently and effectively. It is better than regular python because of it's amazing capabilities. In this article I'm just going to introduce you to the basics of what is mostly required for machine learning and datascience. I'm not going to cover everything that's possible with numpy library.
