The Python Standard Library offers a wide variety of features for programmers. In addition to facilitating the use of data types, exceptions, and functions, it also allows the programmer to work with more complex concepts like input and output streams, command line arguments, and internet data handling.

This library has an extensive list of modules that can be read about here: https://docs.python.org/3/library/

Python Standard Library Modules

The `os` module is a built-in Python library that provides a portable way to use operating system-dependent functionality. It allows programmers to interact with the underlying operating system that Python is running on, enabling tasks such as creating and removing directories, fetching directory contents, changing the current working directory, and constructing file paths robustly. In the context of data preprocessing, the `os` module is essential for preparing the file system, such as creating destination folders for datasets before writing data files to them.
