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.

Let's Build a Dashboard

In the previous chapter, we learned how to create robust pipelines and schedule them so that we have metrics updated every day. With that, our valuable data product is automated! What should we do? Perhaps it is a good moment to discuss dashboards. Dashboards are essentially the entry point for you to monitor the behavior of the system (your service, markets, users, or anything else) via a set of data visualizations. Dashboards help teams and companies to ensure the business is running smoothly or to detect—and adjust tochanges or anomalies. So, to help us understand them better, let's see how they work.

The following topics will be covered in this chapter:

  • Different ways to build a dashboard
  • Building a static dashboard
  • Building and serving a dynamic dashboard
  • Pros and cons of different approaches
  • Debugging Altair
