How to rename a specific range of columns in Python (Pandas) - 


 koak.rename(columns = lambda x : 'koak-' + x, inplace=true)

the above code allows me add 'koak' in front of column headers in data frame want add koak prefix column numbers 4-38. how go doing this?

you can assign columns:

koak.columns = ['koak-' + x if 4 <= <= 38 else x i, x in enumerate(koak.columns, 1)]

example:

koak = pd.dataframe(dict.fromkeys('abcdefg', [12])) koak.columns = ['koak-' + x if 2 <= <= 4 else x                  i, x in enumerate(koak.columns, 1)] print(koak)

prints:

     koak-b  koak-c  koak-d   e   f   g 0  12      12      12      12  12  12  12
