Overview of this book

With the SciPy Stack, you get the power to effectively process, manipulate, and visualize your data using the popular Python language. Utilizing SciPy correctly can sometimes be a very tricky proposition. This book provides the right techniques so you can use SciPy to perform different data science tasks with ease. This book includes hands-on recipes for using the different components of the SciPy Stack such as NumPy, SciPy, matplotlib, and pandas, among others. You will use these libraries to solve real-world problems in linear algebra, numerical analysis, data visualization, and much more. The recipes included in the book will ensure you get a practical understanding not only of how a particular feature in SciPy Stack works, but also of its application to real-world problems. The independent nature of the recipes also ensure that you can pick up any one and learn about a particular feature of SciPy without reading through the other recipes, thus making the book a very handy and useful guide.

Storing and retrieving NumPy arrays

Most realistic applications deal with large datasets and will require results to be stored in persistent media, such as a hard disk. NumPy arrays can be stored in either text or binary format and binary files can be optionally compressed. We start the section by showing you a recipe to store files in text format.

How to do it...

Let us proceed with getting our queries about storing and retrieving NumPy arrays resolved.

Storing a NumPy array in text format

To store a single NumPy array to the disk in text format, use the savetxt...
