Summary  
This chapter introduces a numerical computing library that provides multi-dimensional array structures and optimized functions for fast mathematical operations and array manipulations.  

General domain of usage  
Scientific computing

## What is NumPy?

**`NumPy`** is a library for the **Python programming language**, designed for handling **large, multi-dimensional arrays and matrices** of numerical data. It plays a crucial role in **scientific computing** within Python and finds extensive use across various fields, including **machine learning, data science, and scientific computing**.

The library offers a vast array of functions and tools specifically for managing large volumes of numerical data. Among these capabilities are functions for executing **mathematical operations** on arrays, including computations of the mean, median, standard deviation, and beyond. 

Additionally, `NumPy` equips users with numerous utilities for **array manipulation**, such as sorting, reshaping, and indexing, enhancing its indispensability in numerical and scientific computation.

One of the **key advantages** of `NumPy` is its capability for **fast, efficient computations** on large data arrays. This efficiency is due to the underlying optimized C and Fortran code, allowing `NumPy` to execute computations **much faster** than if using pure Python code.

In this project, we will delve into the fundamentals of NumPy, exploring its core features and uncovering the reasons behind its significant impact on scientific computing. By understanding its architecture and capabilities, we will grasp why it is considered an essential tool for data scientists, researchers, and developers working in the realm of data analysis, machine learning, and beyond.
