Pandas confused

[snippsat]

Except when i print the result
of the subtotal after grouping, it displays 0,1... on top,
are these indexes?

No only 1 are index use df.columns to see,have to reset the index.

>>> df = Qdf.groupby([0]).sum()
>>> df
              1
0              
AF-10   1988.10
AF-20     90.00
BA-40   2850.00
BA-50    150.00
BO-30  16514.61
BR-10    528.35
>>> df.columns
Int64Index([1], dtype='int64')
>>> 
>>> df = df.reset_index()
>>> df.columns
Int64Index([0, 1], dtype='int64')
>>> df
       0         1
0  AF-10   1988.10
1  AF-20     90.00
2  BA-40   2850.00
3  BA-50    150.00
4  BO-30  16514.61
