Crash course of NumPy

Welcome to Numpy. Numpy is a Linear Algebra Library which is almost one of the most important libraries for Data Science with Python. During our machine learning episodes, we will rely on it as one of our main approaches to handle data. In this series, all our discussions are around with NumPy array and we will get familiar with it in 3 steps: creation, indexing and common operations. If your never heard of it, don't worry. In most cases, you can use it fluently with your experiences with normal arrays. So, let's get started.
