# How NumPy Arrays are faster than Python List?

Numpy is the core library for scientific computing in Python. A NumPy array is a grid of values, all of the same type, and is indexed by a tuple of non-negative integers. The Python core library provided Lists. A list is the Python equivalent of an array, but is resizeable and can contain elements of different types.

How is Numpy so fast? In this video we find out how Numpy’s ndarray is stored and how it is usually manipulated by Numpy functions.
