Example 1

In this example, we take a numpy array in arr, and convert this numpy array into list using numpy.tolist().

Python Program

import numpy

arr = numpy.array([[1, 2], [3, 4]])
x = arr.tolist()

print("Numpy Array :\n", arr)
print("List :", x)
Run

Output

Numpy Array :
 [[1 2]
 [3 4]]
List : [[1, 2], [3, 4]]
