Overview of this book

Learn Python Programming, Third Edition is both a theoretical and practical introduction to Python, an extremely flexible and powerful programming language that can be applied to many disciplines. This book will make learning Python easy and give you a thorough understanding of the language. You'll learn how to write programs, build modern APIs, and work with data by using renowned Python data science libraries. This revised edition covers the latest updates on API management, packaging applications, and testing. There is also broader coverage of context managers and an updated data science chapter. The book empowers you to take ownership of writing your software and become independent in fetching the resources you need. You will have a clear idea of where to go and how to build on what you have learned from the book. Through examples, the book explores a wide range of applications and concludes by building real-world Python projects based on the concepts you have learned.

JSON Web Tokens

A JSON Web Token, or JWT, is a JSON-based open standard for creating tokens that assert some number of claims. JWTs are frequently used as authentication tokens. In this context, the claims are typically statements about the identity and permissions of an authenticated user. The tokens are cryptographically signed, which makes it possible to verify that the content of the token has not been modified since it was issued. You can learn all about this technology on the website (https://jwt.io/).

This type of token is comprised of three sections, separated by a dot, in the format A.B.C. B is the payload, which is where we put the claims. C is the signature, which is used to verify the validity of the token, and A is a header, which identifies the token as a JWT, and indicates the algorithm used to compute the signature. A, B, and C are all encoded with a URL-safe Base64 encoding (which we'll refer to as Base64URL). The Base64URL encoding makes it possible to use...
