Last Updated : 17 Sep, 2019

With the help of **Numpy.expand_dims()** method, we can get the expanded dimensions of an array by using Numpy.expand_dims() method.

Syntax : Numpy.expand_dims() Return : Return the expanded array.

**Example #1 :**In this example we can see that using Numpy.expand_dims() method, we are able to get the expanded array using this method.

Python3 1=1 `

import numpy

import numpy as np

using Numpy.expand_dims() method

gfg = np.array([1, 2]) print(gfg.shape)

gfg = np.expand_dims(gfg, axis = 0) print(gfg.shape)

`

Output :

(2, ) (1, 2)

Example #2 :

Python3 1=1 `

import numpy

import numpy as np

using Numpy.expand_dims() method

gfg = np.array([[1, 2], [7, 8]]) print(gfg.shape)

gfg = np.expand_dims(gfg, axis = 0) print(gfg.shape)

`

Output :

(2, 2) (1, 2, 2)
