INTRODUCTION
NumPy is one of the most fundamental libraries in Python and perhaps the
most useful of them all. NumPy handles large datasets effectively and
efficiently.
NumPy stands for Numerical Python and is one of the most useful scientific
libraries in Python programming. It provides support for large
multidimensional array objects and various tools to work with them. NumPy
arrays are called ndarray or N-dimensional arrays and they store
elements of the same type and size
Numpy installation
pip install numpy
import numpy as np
