Python实现把多维数组展开成DataFrame

如下所示： import numpy as np import pandas as pd ################# 准备数据 ################# a1 = np.arange(1,101) a3 = a1.reshape((2,5,10)) a3 ''' array([[[ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10], [ 11, 12, 13, 14, 15, 16, 17, 18, 19, 20], [ 21, 22, 23, 24, 25, 26, 27, 28, 29, 30], [ 31, 32, 33, 34, 35, 36
