Numpy

backbone of ML

Num - Numerical

Py - Python

It consists of two parts mainly:

1. ndarray - n dimensional array

2. Ufunc - Universal functions

import numpy as np
print(np.__version__)

# Create a numpy array

x = np.array([1,3,5,7])
print(x)
print(type(x))
print(x[-4])
print(np.ndim(x))
print(x.shape)
print(x.dtype)

# Create a numpy array

x = np.array((1,3,5,7)) # not a common way
print(x)
print(type(x))
print(x[-4])
print(np.ndim(x))
print(x.shape)
print(x.dtype)
