Mapping values from one column to another column in separate dataframes on the basis of common column

Question

I have two dataframe:

import pandas as pd

create the first data frame

df1

id  name

0 1 John

1 2 Mary

2 3 David

3 4 Lisa

df2

id age

0 2 35

1 44 28

2 11 42

3 3 19

I was trying to get values of 'name' column in df1 replaced by values of 'age' column of df2 but only where id has common values. I am trying to get this output

id  name

0 1 John

1 2 35

2 3 19

3 4 Lisa
