In this section, we will explore our first Python-based server, which will be a RESTful API server implemented using the Flask-RESTful framework for Python.
A RESTful API (REST stands for Representational State Transfer) is a software design pattern used for building web service APIs. It's a flexible pattern that is both technology- and protocol-independent. Its technology independence helps to promote interoperability between different technologies and systems, including different programming languages. And although it does promote protocol independence, it's frequently and almost always by default (or, at the least, assumed to be) built on top of the HTTP protocol used by web servers and web browsers.
RESTful APIs are the most common technique used today for building web services and APIs. In fact, it's so common that many people learn about them and use the design pattern without ever understanding what they are...
