numpy.moveaxis()函数| Python

numpy.moveaxis()函数将数组的轴移动到新位置。其他轴保持原来的顺序。

Syntax : numpy.moveaxis(arr, source, destination)
Parameters :
arr : [ndarray] input array.
source : [ int or sequence of int] Original positions of the axes to move. These must be unique.
destination : [ int or sequence of int] Destination positions for each of the original axes. These must also be unique.
Return : [ndarray] Array with moved axes. This array is a view of the input array.

代码#1：

# Python program explaining
# numpy.moveaxis() function
  
# importing numpy as geek 
import numpy as geek
  
arr = geek.zeros((1, 2, 3, 4))
  
gfg = geek.moveaxis(arr, 0, -1).shape
  
print (gfg)

输出 ：

(2, 3, 4, 1)
