Index to column

Question

I tried to convert my Index to a column. But I get the Error: AttributeError: 'DataFrame' object has no attribute 'reset_Seriennummer' It should be simple but it doesn't work.

My Index is ot called Index but it is written the same way:

My df:

Seriennummer    0
701085.0    "(array([1.52558046e+03, 2.55900548e+02, 5.96901108e-01]), array([[ 9.41414894e+03, -2.07982124e+03, -2.30130078e+00],
       [-2.07982124e+03,  1.44373786e+03,  9.59282709e-01],
       [-2.30130078e+00,  9.59282709e-01,  7.75807643e-04]]))"
701086.0    "(array([1.19304206e+03, 2.71174688e+02, 6.59205468e-01]), array([[ 5.21906135e+03, -2.23855187e+03, -2.11896425e+00],
       [-2.23855187e+03,  2.61036500e+03,  1.67396324e+00],
       [-2.11896425e+00,  1.67396324e+00,  1.22581746e-03]]))"

What I tried so far:

df['Seriennummer'] = df.Seriennummer

or

df.reset_Seriennummer(level=0, inplace=True)

Answer 1

This will work:

df.reset_index(level='Seriennummer')
