Overview of this book

In today’s world of science and technology, it’s all about speed and flexibility. When it comes to scientific computing, NumPy tops the list. NumPy gives you both the speed and high productivity you need. This book will walk you through NumPy using clear, step-by-step examples and just the right amount of theory. We will guide you through wider applications of NumPy in scientific computing and will then focus on the fundamentals of NumPy, including array objects, functions, and matrices, each of them explained with practical examples. You will then learn about different NumPy modules while performing mathematical operations such as calculating the Fourier Transform; solving linear systems of equations, interpolation, extrapolation, regression, and curve fitting; and evaluating integrals and derivatives. We will also introduce you to using Cython with NumPy arrays and writing extension modules for NumPy code using the C API. This book will give you exposure to the vast NumPy library and help you build efficient, high-speed programs using a wide range of mathematical features.

Preface

Distributing your application


Once all the development for your module/application is complete and you are ready with your complete working application and setup file, the next task will be to share your hardwork with the World to benefit others. The steps to release it to the world by using PyPI are quite straightforward. The first thing you need to do as an author of a package is to register yourself. You can do it directly from the command line as follows:

    $ python setup.py register
    running register
    running egg_info
    ....
    ....
    We need to know who you are, so please choose either:
     1. use your existing login,
     2. register as a new user,
     3. have the server generate a new password for you (and email it to you), or
     4. quit
    Your selection [default 1]:

Tip

This process will fail if you do not have proper metadata information of any file missing in your setup.py. Make sure you have setup.py working...
