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.

Shell

Every operating system, by definition, has some sort of interface to work with. Most people use the graphical user interface (GUI), as it is easy to understand and navigate, and does not require any specific knowledge. However, graphical interfaces are complex, demanding, and not reproducible. Even before the GUI existed, programmers used code-based interfaces to interact with computers—shells. Both macOS and Linux systems are Unix-based and, hence, leverage the same shell interface, Bash. Windows, on the other hand, has two, a very basic command prompt, and a PowerShell (which we recommend using). There are also ways to install and use Bash on Windows. All those systems allow you to create, change, and delete files and folders, run programs and utilities, and so on. In addition, because those systems are based on textual commands (code, essentially), commands can...
