    ...: 
    ...: upper = pd.DataFrame([[50., 80.,49.], [100.,100.,90.]], columns=['B', 'C','A'])
    ...: 
    ...: lower = pd.DataFrame([[60., 40.,35.], [90.,95.,85.]], columns=['C', 'B','A'])
    ...: 
    ...: 

In [12]: df1
Out[12]: 
      A     B      C
0  50.0  60.0   70.0
1  80.0  90.0  100.0

In [16]: lower[df1.columns]
Out[16]: 
      A     B     C
0  35.0  40.0  60.0
1  85.0  95.0  90.0

In [17]: upper[df1.columns]

**After**
```python
