How to get dimension of NumPy array

You can get the dimension of the NumPy array with the following code. If you want to learn Python, I highly recommend reading This Book.

Example 1

import numpy as np

a = np.array([5, 10, 15, 20])

print(a.ndim)

Output:

import numpy as np

a = np.array(5)

print(a.ndim)

Output:

import numpy as np

a = np.array([[5, 10, 15],[20, 25, 30]])

print(a.ndim)

Output:

import numpy as np

a = np.array([[[5, 10, 15],[20, 25, 30],[35, 40, 45]]])

print(a.ndim)

Output:

import numpy as np

a = np.array([[ [[5, 10, 15]],[[20, 25, 30]],[[35, 40, 45]] ]])

print(a.ndim)

Output:
