所以我读了一个29列的数据表,我在一个索引列中添加(总共30个)。Python pandas.core.indexing.IndexingError:不可对齐的布尔系列键提供
Data = pd.read_excel(os.path.join(BaseDir, 'test.xlsx'))
Data.reset_index(inplace=True)
然后,我想子集的数据只包括列名称包含“ref”或“Ref”的列;我下面的代码从另一个叠后:
col_keep = Data.ix[:, pd.Series(Data.columns.values).str.contains('ref', case=False)]
不过,我不断收到此错误:
print(len(Data.columns.values))
30
print(pd.Series(Data.columns.values).str.contains('ref', case=False))
0 False
1 False
2 False
3 False
4 False
5 False
6 False
7 False
8 False
9 False
10 False
11 False
12 False
13 False
14 False
15 False
16 False
17 False
18 False
19 False
20 False
21 False
22 False
23 False
24 True
25 True
26 True
27 True
28 False
29 False

所以布尔值是正确的,但它为什么不工作?为什么错误不断弹出?
