python - 更改行顺序 Pandas 数据框

Question

我在 python3 的 pandas 中有以下数据框:

               +------------------------------+
               | total_sum | percent_of_total |
+--------------+------------------------------+ 
| Group        |           |                  |
+--------------+------------------------------+     
| 11-          | 99435     | 0.255880         |
+--------------+-----------+------------------+
| Bachelor+    | 64900     | 0.167010         |
+--------------+-----------+------------------+
| Just 12      | 162483    | 0.418124         |
+--------------+-----------+------------------+
| Some College | 61782     | 0.158986         |
+---------------------------------------------+

我想像这样更改包括索引在内的行的顺序...

               +------------------------------+
               | total_sum | percent_of_total |
+--------------+------------------------------+ 
| Group        |           |                  |
+--------------+------------------------------+     
| 11-          | 99435     | 0.255880         |
+--------------+-----------+------------------+
| Just 12      | 162483    | 0.418124         |
+--------------+-----------+------------------+
| Some College | 61782     | 0.158986         |
+--------------+-----------+------------------+
| Bachelor+    | 64900     | 0.167010         |
+--------------+-----------+------------------+

我尝试使用 .sort_index(['11-', 'Just 12', 'Some College', 'Bachelor+']) 并收到以下错误... TypeError:无法散列的类型:'list'。所以看起来 pandas 按字母顺序对这些索引进行排序。如何重新排序行？

尝试使用 .reindex:

.reindex(['11-', 'Just 12', 'Some College', 'Bachelor+'])
