## Python Numpy

By default Python does not have a concept of Arrays. And there is no inbuilt support for multidimensional arrays.

Python Numpy is a library that handles multidimensional arrays with ease. It has a great collection of functions that makes it easy while working with arrays. Especially with the increase in the usage of Python for data analytic and scientific projects, numpy has become an integral part of Python while working with arrays.
