Python 无法筛选数据帧中的索引

Python 无法筛选数据帧中的索引,python,pandas,dataframe,Python,Pandas,Dataframe,这是我的pivot\u设备\u T.索引,我的数据帧是pivot\u设备 Index(['', '3', 'AXIS', ... , 'All_Bolt', 'All_Telkomsel', 'All_XL', 'All_Indosat', 'All_Smartfren'], dtype='object', name='operatorName') 我现在做的是 pivot_device_T = pivot_device_T[pivot_device_T['index'].str.

这是我的
pivot\u设备\u T.索引
,我的数据帧是
pivot\u设备

Index(['', '3', 'AXIS', ... , 'All_Bolt', 'All_Telkomsel', 'All_XL', 'All_Indosat', 'All_Smartfren'],
      dtype='object', name='operatorName')
我现在做的是

pivot_device_T = pivot_device_T[pivot_device_T['index'].str.contains("All")]
但我得到的是

KeyError:“索引”

使用
pivot\u device\u T.index
,因为
pivot\u device\u T['index']
选择列名
index
,并且因为不存在它会引发错误:

pivot_device_T = pivot_device_T[pivot_device_T.index.str.contains("All")]
另一个解决办法应该是:

pivot_device_T = pivot_device_T.filter(like='All', axis=0)
