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.

Summary

In this chapter, we learned to build two similar dashboardsa static one, with no server needed and using Altair, and a dynamic one, built from an ordinary Jupyter Notebook with arbitrary code and visualization packages, using the panel package. We discussed the pros and cons of each approach and when to select one over the other.

Either way, the dashboard is a great way to communicate your data product to your colleagues and clients. Dashboards allow us to get insights into business processes and spot issues early on. In many cases, that would make a perfect deliverable. In some cases, though, you might need to create a programmatic access point for your code, for example, a machine learning algorithm for an external application (a website, mobile app, or some analyst from their Jupyter Notebook) to use.

In the next chapter, we'll do exactly that, by building...
