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])
