How to Check How Many Dimensions Arrays Have

In this example we will show how to check how many dimensions the NumPy arrays have in Python.

Source Code

import numpy as np

i = np.array(8)
j = np.array([1, 2, 3, 4])
k = np.array([[1, 2], [3, 4], [5, 6]])
n = np.array([[[1, 2], [3, 4]], [[5, 6], [7, 8]]])

print(i.ndim)
print(j.ndim)
print(k.ndim)
print(n.ndim)

Output:

0
1
2
3
