A common need to is to from a Python list to a numpy array and back. Let's learn how to do both.
import numpy as np # python list to numpy array arr = np.array([1, 2, 3, 4]) print(arr) # numpy array to python list lst = list(arr) print(lst)
And that's it! To go from a list to a numpy array, we use the
np.array function. To return from
a numpy array back to a python list, we use the
