numpy.swapaxes()函数| Python

numpy.swapaxes()函数交换数组的两个轴。

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.

代码#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)

输出 ：

[[2]
 [4]
 [6]]

代码#2：

# Python program explaining
# numpy.swapaxes() function
  
# importing numpy as geek 
import numpy as geek
  
arr = geek.array([[[0, 1], [2, 3]], [[4, 5], [6, 7]]])
  
gfg = geek.swapaxes(arr, 0, 2)
  
print (gfg)

输出 ：

[[[0 4]
  [2 6]]
 [[1 5]
  [3 7]]]
