我有以下形式的数据：

red_id            test1 test2   test3......
815298969_mid1    pass  fail    pass
815298969_mid2    fail  pass    pass
815298969_final   pass  pass    pass
814248989_mid1    pass  fail    fail
814248989_mid2    pass  fail    pass
814248989_final   pass  pass    fail
816592961_mid1    fail  pass    pass
816592961_mid2    pass  pass    pass
816592961_final   pass  pass    pass
......

我有一个带有上述学生详细信息的熊猫数据框，我按“red_id”列对其进行分组

    grouped = data_frame.groupby('red_id')

.....然后在我的脚本中我有循环

for red, stud_data in grouped:
......
        data = data.drop('red_id', axis=1)

我正在尝试从数据框中删除列“red_id”，因为我希望在 for 循环中通过/失败的类平均值，如上所示。它给了我例外：
