*****************************************************************
Full code from the video:
import numpy as np
Creation of a sample array
array_a = np.array([1,2,3,4,5])
print(array_a)
We can add elements of multiple data types to python lists, not arrays
print([1,2,3,4,5, 'derrick'])
print(array_a.shape) # View the shape of an array by the shape attribute
array_b = np.array([[1,2,3,4,5],[1,2,3,4,5]]) # Multidimensional arrays
print(array_b.shape)
