# 1.1. Numpy¶

NumPy is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays.

## 1.1.1. Rationale¶

NumPy is the fundamental package for scientific computing with Python. It contains among other things:

• a powerful N-dimensional array object

• tools for integrating C/C++ and Fortran code

• useful linear algebra, Fourier transform, and random number capabilities

Besides its obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide variety of databases.

## 1.1.2. Installation¶

Installation:

$pip install numpy  Upgrade: $ pip install --upgrade numpy


Check version:

>>> import numpy as np
