What is NumPy and Why Use It?

NumPy is a Python library that makes working with numerical data faster and more efficient.

It helps you store large datasets compactly and perform mathematical operations at high speed.

Unlike regular Python lists, NumPy provides arrays, which are optimized for numerical computation.

Install NumPy using Python’s package manager pip:

Copy
pip install numpy

You can import NumPy using the import keyword as follows:

Copy
import numpy as np

np is a common alias for numpy.
