NumPy 数组操作 numpy.ndarray.T 此函数属于 ndarray 类。它的行为类似于 numpy.transpose 。 示例 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.TPythonCopy 以上程序的输出结果为: 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]] PythonCopy
