how to get shape of a numpy array code example

Example 1: code for dimensions in numpy

import numpy as np

arr = np.array([1, 2, 3, 4])
arr_2D = np.array([[1, 2, 3, 4, 5], [6, 7, 8, 9, 10]])

print(arr.ndim)
print(arr_2D.ndim)

Example 2: numpy shape

>>> a = np.array([(1, 2), (3, 4)], dtype=[('x', 'i4'), ('y', 'i4')])
>>> np.shape(a)
(2,)
>>> a.shape
(2,)
