Create an array

You can use the NumPy package to create arrays. NumPy arrays are optimized for numerical analyses and contain only a single data type. To convert a list to an array, you can use the array() function from NumPy. 

import numpy as np

a_list = [1, 2, 3, 4]
a_list

[1, 2, 3, 4]

an_array = np.array(a_list)
an_array

array([1, 2, 3, 4])
