NumPyndarray.T函数

该函数属于 ndarray 类。它的行为类似于 numpy.transpose 。

import numpy as np 
a=np.arange(12).reshape(3,4) 

print 'The original array is:' 
print a 
print '\n'  

print 'Array after applying the function:' 
print a.T

The original array is:
[[ 0 1 2 3]
 [ 4 5 6 7]
 [ 8 9 10 11]]

Array after applying the function:
[[ 0 4 8]
 [ 1 5 9]
 [ 2 6 10]
 [ 3 7 11]]
