Python numpy.swapaxes()用法及代碼示例

numpy.swapaxes()函數互換數組的兩個軸。

用法： numpy.swapaxes(arr, axis1, axis2)

參數：

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.

代碼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)

輸出：

[[2]
 [4]
 [6]]

代碼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)

輸出：

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