Python libraries

Definition

Python libraries are collections of pre-written code that allow users to perform a variety of tasks without having to write code from scratch. They provide functions and methods to streamline processes like numerical integration, making complex computations more accessible and efficient for programmers. Utilizing these libraries can significantly reduce development time and help with tasks like data analysis, visualization, and numerical methods.
