正确的对DataFrame reverse运算

data.reindex(index=data.index[::-])

or simply:

data.iloc[::-]

will reverse your data frame, if you want to have a for loop which goes from down to up you may do:

for idx in reversed(data.index):

    print(idx, data.loc[idx, 'Even'], data.loc[idx, 'Odd'])

or

for idx in reversed(data.index):

    print(idx, data.Even[idx], data.Odd[idx])
