In this lesson, we will introduce the NumPy library in Python.

What is NumPy?

NumPy is a Python library for scientific computing. NumPy stand for Numerical Python. Here is the official description of the library from its website:

"NumPy is the fundamental package for scientific computing with Python. It contains among other things:

  • a powerful N-dimensional array object
  • sophisticated (broadcasting) functions
  • tools for integrating C/C++ and Fortran code
  • useful linear algebra, Fourier transform, and random number capabilities

Besides its obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide variety of databases.

NumPy is licensed under the BSD license, enabling reuse with few restrictions."

NumPy is such an important Python library that there are other libraries (including pandas) that are built entirely on NumPy.
