NumPy Beginner's Guide - Second Edition

By: Ivan Idris

Overview of this book

NumPy is an extension to, and the fundamental package for scientific computing with Python. In today's world of science and technology, it is all about speed and flexibility. When it comes to scientific computing, NumPy is on the top of the list. NumPy Beginner's Guide will teach you about NumPy, a leading scientific computing library. NumPy replaces a lot of the functionality of Matlab and Mathematica, but in contrast to those products, is free and open source. Write readable, efficient, and fast code, which is as close to the language of mathematics as is currently possible with the cutting edge open source NumPy software library. Learn all the ins and outs of NumPy that requires you to know basic Python only. Save thousands of dollars on expensive software, while keeping all the flexibility and power of your favourite programming language.You will learn about installing and using NumPy and related concepts. At the end of the book we will explore some related scientific computing projects. This book will give you a solid foundation in NumPy arrays and universal functions. Through examples, you will also learn about plotting with Matplotlib and the related SciPy project. NumPy Beginner's Guide will help you be productive with NumPy and have you writing clean and fast code in no time at all.

Time for action – installing NumPy, Matplotlib, SciPy, and IPython on Linux


Most Linux distributions have NumPy packages. We will go through the necessary steps for some of the popular Linux distros:

  1. Run the following instructions from the command line for installing NumPy and Red Hat:

    yum install python-numpy
    
  2. To install NumPy on Mandriva, run the following command-line instruction:

    urpmi python-numpy
    
  3. To install NumPy on Gentoo run the following command-line instruction:

    sudo emerge numpy
    
  4. To install NumPy on Debian or Ubuntu, we need to type the following :

    sudo apt-get install python-numpy
    

The following table gives an overview of the Linux distributions and corresponding package names for NumPy, SciPy, Matplotlib, and IPython.
