  • Last Updated : 22 Apr, 2020

numpy.swapaxes() function interchange two axes of an array.

Syntax : numpy.swapaxes(arr, axis1, axis2)
Parameters :
arr : [array_like] input array.
axis1 : [int] First axis.
axis2 : [int] Second axis.
Return : [ndarray] In earlier NumPy versions, a view of arr is returned only if the order of the axes is changed, otherwise the input array is returned. For NumPy >= 1.10.0, if arr is an ndarray, then a view of arr is returned; otherwise a new array is created.

Code #1 :




# Python program explaining
# numpy.swapaxes() function
  
# importing numpy as geek 
import numpy as geek
  
arr = geek.array([[2, 4, 6]])
  
gfg = geek.swapaxes(arr, 0, 1)
  
print (gfg)


Output :

[[2]
 [4]
 [6]]

 
Code #2 :

gfg = geek.swapaxes(arr, 0, 2)
  
print (gfg)
