1.1 Creating Arrays

import numpy as np

list1 = [6, 7.5, 8, 0, 1]
array1 = np.array(list1)
array1

array([6. , 7.5, 8. , 0. , 1. ])

list2 = [ [1, 2, 3, 4], [5, 6, 7, 8] ]
array2 = np.array(list2)
array2

array([[1, 2, 3, 4],
       [5, 6, 7, 8]])

1.2 Arrays Dimensions

array2.ndim

2

1.3 Arrays Shape

array2.shape

(2, 4)

1.4 Arrays Data Types

array1.dtype

dtype('float64')

array2.dtype

dtype('int64')
