本文介绍了Python中transpose函数的使用方法，通过实例解析了如何对矩阵或数组进行转置操作，适用于数据处理和矩阵运算场景。

示例

import numpy as np

a=np.arange(24).reshape((2,3,4))

print("origin:\n",a,"\nsize:",a.shape)
print("\na.transpose((0,1,2)):\n",a.transpose((0,1,2)),"\nsize:",a.transpose((0,1,2)).shape)
print("\na.transpose((0,2,1)):\n",a.transpose((0,2,1)),"\nsize:",a.transpose((0,2,1)).shape)
print("\na.transpose((1,0,2)):\n",a.transpose((1,0,2)),"\nsize:",a.transpose((1,0,2)).shape)
print("\na.transpose((1,2,0)):\n",a.transpose((1,2,0)),"\nsize:",a.transpose((1,2,0)).shape)
print("\na.transpose((2,0,1)):\n",a.transpose((2,0,1)),"\nsize:",a.transpose((2,0,1)).shape)
print("\na.transpose((2,1,0)):\n",a.transpose((2,1,0)),"\nsize:",a.transpose((2,1,0)).shape)

输出：

origin:
 [[[ 0  1  2  3]
  [ 4  5  6  7]
  [ 8  9 10 11]]
 [[12 13 14 15]
  [16 17 18 19]
  [20 21 22 23]]] 
size: (2, 3, 4)

a.transpose((0,1,2)):
 [[[ 0  1  2  3]
  [ 4  5  6  7]
  [ 8  9 10 11]]
 [[12 13 14 15]
  [16 17 18 19]
  [20 21 22 23]]] 
size: (2, 3, 4)

a.transpose((0,
