Learn Python by Building Data Science Applications

By: Philipp Kats, David Katz

Overview of this book

Python is the most widely used programming language for building data science applications. Complete with step-by-step instructions, this book contains easy-to-follow tutorials to help you learn Python and develop real-world data science projects. The “secret sauce” of the book is its curated list of topics and solutions, put together using a range of real-world projects, covering initial data collection, data analysis, and production. This Python book starts by taking you through the basics of programming, right from variables and data types to classes and functions. You’ll learn how to write idiomatic code and test and debug it, and discover how you can create packages or use the range of built-in ones. You’ll also be introduced to the extensive ecosystem of Python data science packages, including NumPy, Pandas, scikit-learn, Altair, and Datashader. Furthermore, you’ll be able to perform data analysis, train models, and interpret and communicate the results. Finally, you’ll get to grips with structuring and scheduling scripts using Luigi and sharing your machine learning models with the world as a microservice. By the end of the book, you’ll have learned not only how to implement Python in data science projects, but also how to maintain and design them to meet high programming standards.

Trying SciPy and scikit-learn

The SciPy package essentially kicked off the entire era of scientific Python. Created in 2001 by researchers Travis Oliphant, Pearu Peterson, and Eric Jones, it was formed as a collection of basic and universal scientific techniques. Over time, the package grew and now offers generic tooling and popular techniques for scientific analysis. Its submodules cover linear algebra, integration, optimization, interpolation, statistics, and many more.

With the rise of machine learning, the corresponding submodule of SciPy grew more and more complex. At some point, it became so big, the decision was made to reintroduce it as a separate, independent package—scikit-learn. As the mark of its origins, the package kept its name, defined earlier as SciPy kit—learn. Due to its simple and unified interface and a large variety of models, scikit-learn quickly...
