Hi and welcome to numpy tutorials section. 

What is numpy?

     Numpy is a package in python which is used for scientific calculations. It helps in working with multidimensional arrays. The numpy arrays are efficient in storage and effective in computations.

     All the elements in a numpy array should be of same type.

How to install numpy ?

     I am going to discuss 2 methods to install numpy here.

Method 1.) Download and install Anacondas :

     If you have not yet installed python in your machine, I highly recommend you to install Anacondas as it has python and lot of other useful packages (including numpy) for data science pre-installed.

You can install the latest version of Anacondas from here: https://www.continuum.io/downloads

Method 2.) Install Latest version of Python from : https://www.python.org/downloads/

Once Python is installed, open command prompt and navigate to scripts folders where you have installed the python. You can enter the following command to install numpy.

pip install numpy
