How to Check How Many Dimensions Arrays Have


In this example, we will learn 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)
