Introduction of Python Libraries

The module is a file with some Python code and a package is a directory for modules or sub packages. There is only a minor difference between a package and a Python library, and it is quite blurred. A Python library is a reusable chunk of code that you can include into your projects. When compared to other programming languages like C or C++, Python libraries don’t pertain to a specific context in Python. A python library defines a collection of core modules. A package is a library that can be installed using package managers.

Python Standard Library

The Python Standard Library is a collection of tokens, syntax, or semantics in Python. It is bundled with core Python distribution and written in C programming language. It handles the core functionalities of core modules in Python. There are more than 200 core modules at the heart of the Python standard library. In addition to this, you may also access a growing collection of thousands of components from the Python Package Index.
