pandas map column data based on value from another column using if to determine which dict to use

Question

I have the following dataframe:

df = pd.DataFrame([[\'Person1\', \'CT\', 2017],
               [\'Person2\', \'FL\', 2017],
               [\'Person3\', \'T         


        

Answer 1

Use np.where:

df['New_State_Name'] = np.where(df['Name']=='Person1',df['State'].map(state_map),df['State'].map(state_map2))

Output:

      Name State  Year New_State_Name
0  Person1    CT  2017    Connecticut
1  Person2    FL  2017    BBC-Florida
2  Person3    TX  2017         CDA-TX
3  Person1    TX  2016          Texas
