Numpy (Numerical Python) 1.23.3

Complex library that supports many versions of Python, and can be used inside commercial environments.

Numpy is a library that was especially intended for scientific computing, and comes with a variety of array and derived objects, including matrices, arrays, and collection of routines that achieve the completion of operations in a shorter time.

It was designed to be helpful in a variety of domains that are related to mathematics, (e.g. linear algebra, Fourier transformations, statistics, simulations, etc), while also adding array support for Python, as a data structure fit for numerical-related endeavors, and they will be assigned a fixed size from the start while only containing data of the same type.

It will facilitate working with large data sets thanks to its approach and the properties of its data structure, which will allow the programmer to perform mathematical-related operations in fewer lines of code, which will be more efficient.

Numpy is a complex library that comes with support for many versions of Python, and since it's an open-source project, it means it can be used inside commercial environments.
