numpy.ndarray.T numpy.transpose numpy.rollaxis 该函数属于 ndarray 类。它的行为类似于 numpy.transpose 。 例 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 上述计划的输出将是 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]] numpy.transpose numpy.rollaxis
