How can i pivot down my row values for each row in pandas dataframe? [closed]

Answer 1

You can use stack, reset_index and rename column 0:

print df.set_index(['Name', 'Percent']).stack().reset_index(level=[0,1])
                                       .reset_index(drop=True).rename(columns={0:'Subject'})
     Name  Percent  Subject
0  ramesh       85    Maths
1  ramesh       85  Science
2     ram       42    Maths
3     Raj       85  Science
