Python libraries

Definition

Python libraries are collections of pre-written code that developers can use to add functionality to their Python programs without having to write everything from scratch. These libraries provide tools and functions for various tasks, including data filtering and smoothing techniques, which are crucial in processing and analyzing data effectively.
