Numpy Introduction

Now that we have all the basic knowledge of Python it’s time to study the advanced topcs. Numpy is a library used for scientific computing. It gives us access to multi dimensional array objects and different functions to manipulate those arrays and data structures. Numpy also allows us to integrate C/C++ code with Python and gives us wide range of mathematical functions as well. These mathematical functions include Fourier transforms, Linear Algebraic models and random number generators.

Numpy Installation

To use Numpy it’s recommended to use SciPy known as Scientific Python. To use Scientific Python we recommend downloading and installing a software called Anaconda. Latest version can be downloaded from the link below.

https://www.anaconda.com/distribution/

Another way is to install Numpy using a package manager such as Pip. Details of Pip are already discussed in the previous tutorials. If package manager is already setup then we can run the following command.

pip install numpy

For using Numpy we can simply import it in the required file.

import numpy

Uses of Numpy

  1. Numpy arrays are faster then lists in Python.
  2. Numpy allows only same type of data in each column thus allowing us to maintain data in specifically formatted columns.
  3. It provids a N dimensional array object which has immense usage in Linear Algebraic equations.
  4. Numpy is an alternative to MATLAB
  5. Numpy is used in complex scientific computing applications

Virus note: All files are scanned once-a-day by SourceCodester.com for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.

FOR YOUR OWN SAFETY, PLEASE:

1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
