Since the intent of the question is not clear, if you want to create a hierarchical index, you can achieve this in the following way

import pandas as pd

idx = pd.MultiIndex.from_product(([21,22],[1,2,3,4,5],[60,70,80,90,100]), names=["uselevel","class","upper"])
pd.DataFrame(index=idx, columns=['column1','column2','column3'])

df.head(10)
            column1 column2 column3
uselevel    class   upper           
21  1   60  NaN NaN NaN
        70  NaN NaN NaN
        80  NaN NaN NaN
        90  NaN NaN NaN
       100  NaN NaN NaN
    2   60  NaN NaN NaN
        70  NaN NaN NaN
        80  NaN NaN NaN
        90  NaN NaN NaN
       100  NaN NaN NaN
