Introduction

In the previous chapters, you saw how we can create our own classes incorporating logic and data. Yet, you often don't need to do that — you can rely on the standard library's functions and classes to do most of the work.

The Python standard library consists of modules that are available on all implementations of the language. Every installation of Python will have access to these without the need for any further steps for the modules defined in the standard library

While other famous languages don't have a standard library (such as JavaScript, which, as of 2019, is looking at implementing one), others have what seems to be an extensive set of tooling and functionality. Python goes a step further by including a vast number of basic utilities and protocol implementations as part of the default installation of the interpreter.
