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.

Cookiecutter

Another tool we find useful is Cookiecutter. In a nutshell, this is a templating engine for projects. There are two main scenarios where Cookiecutter can be useful.

First, if you are usually working on multiple projects of a similar structure or purpose, you may save some time and emotion by creating a single template of the project. That includes the folder structure, its name, the default files or templates to include, Makefiles (https://krzysztofzuraw.com/blog/2016/makefiles-in-python-projects.html), proper gitignore settings, and anything else you want. Specific variables can be injected into any text-based files, depending on your selection and configurations. As an illustration, in our practice, we adopted our own templates for our routine data analysis requests.

Second (and specific to programming), building a web app, package, library, or anything based on...
