Answer 1

Hi@shanmugam,

You can change your column by using rename function. I have attached one example below for your reference.

import pandas as pd
df = pd.read_csv('marks.csv')
df
     Distance      Price
0     2                  20
1     4                  40
2     7                  70
3     9                  90

df.rename(columns={'Distance':'dist','Price':'pri'})
     dist                pri
0     2                  20
1     4                  40
2     7                  70
3     9                  90
