python - 从 3 个列表中创建数据框/numpy 数组

Question

我正在尝试从这三个列表中创建一个矩阵或数据框：

x = ["col1","col2","col3","col4","col5","col6","col7","col8","col9","col10"]
y = ["a","b","c"]
z = [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]

我的目标是获得一个如下所示的数据框：

  col1 col2 col3 col4 col5 col6 col7 col8 col9 col10
a   1    2   3    4    5   6     7    8    9    10
b   11   12  13   14   15  16    17   18   19   20 
c   21   22  23   24   25  26    27   28   29   30

IIUC

pd.DataFrame(np.array(z).reshape(len(y),-1),index=y,columns=x)
Out[550]: 
   col1  col2  col3  col4  col5  col6  col7  col8  col9  col10
a     1     2     3     4     5     6     7     8     9     10
b    11    12    13    14    15    16    17    18    19     20
c    21    22    23    24    25    26    27    28    29     30
