NumPy ndarray.dtype Property | Get Data Type of Elements in Array

Last Updated : 15 Jul, 2025

The ndarray.dtype attribute returns the data type of the array’s elements.

This attribute is read-only and cannot be modified directly.

import numpy as geek 
   
arr = geek.array([[0, 1], [2, 3]])
 
gfg = arr.dtype
 
print (gfg)

Output :

int64

Syntax: numpy.ndarray.dtype 

Parameters : None 

Return : [numpy dtype object] Return the data-type of the array’s elements.

To check the data type of NumPy array elements we use ndarray.dtype attribute of the NumPy library in Python

Let us look at the example to understand it better.

import numpy as geek 
   
arr = geek.array([  0.,  1.,  2.])
 
gfg = arr.dtype
 
print (gfg)

Output :

float64
