How to add numbers above a pandas dataframe's column names?

Question

Let's say I have this dataframe:

    Name   Salary  Field
0   Megan  30000   Botany
1   Ann    24000   Psychology
2   John   24000   Police
3   Mary   45000   Genetics
4   Jay    60000   Data Science

I want to add some 0-indexed numbers above the column names, but I'd also want to keep the column names. I want to reach this form:

     0       1       2
    Name   Salary  Field
0   Megan  30000   Botany
1   Ann    24000   Psychology
2   John   24000   Police
3   Mary   45000   Genetics
4   Jay    60000   Data Science

How can I do that with pandas and Python?

Answer 1

You don't need to create a new dataframe:

df.columns = pd.MultiIndex.from_tuples(list(enumerate(df)))

As expected:

#        0      1             2
#     Name Salary         Field
# 0  Megan  30000        Botany
# 1    Ann  24000    Psychology
# 2   John  24000        Police
# 3   Mary  45000      Genetics
# 4    Jay  60000  Data Science

I hope this helps.

Here is a quick way

new_df = pd.DataFrame(df.values,
                      columns = [ list(range(df.shape[1])), df.columns]
                      )

I'm sure there is a more elegant way
