熊猫定位单个行标签并将结果转换为数据框

Question

我有以下df，

    sequence_num object_id employee_id action_code
0            1    291877        4758     APPROVE
1            0    291877        4758      SUBMIT
2            1    291876        4758     APPROVE
3            0    291876        4758      SUBMIT

df.loc[0]给予了

sequence_num    1
object_id       291877
employee_id     4758
action_code     APPROVE   
Name: 0, dtype: object

我想知道如何进入DataFrame。

    sequence_num object_id employee_id action_code
0            1    291877        4758     APPROVE
