Numpy

Numpy is the backbone of Machine Learning in Python.

Numpy stands for Numerical Python.

It consists broadly of two things:

ndarray: n-dimensional array

Ufuncs: Universal Functions

Numpy is superfast because it has vectorized function.

ndarray:

import numpy
print(numpy.__version__)
1.19.2
import numpy as np # de facto standard to label it as np
print(np.__version__)
1.19.2
np.array( list/tuple )
