how to remove index in df Row?

[scidam]

If I understood you correctly, the sample below could be useful for you:

import pandas as pd
dfb = pd.DataFrame({'setup': ['1,2,3,4', '4,5,6,7', '6,7,8,4']})
dfa = pd.DataFrame(dfb['setup'].str.split(',').values.tolist(), columns=['one', 'two', 'three', 'four'])
