How to reverse the order of first and last name in a Pandas Series

Question

I have a pandas series:

names = pd.Series([
\'Andre Agassi\',
\'Barry Bonds\',
\'Christopher Columbus\',
\'Daniel Defoe\',
\'Emilio Estevez\',
\'Fred Flintstone\         


        

Answer 1

With and without using str.replace?

In [451]: names.str.split().apply(lambda x: ', '.join(x[::-1]))
Out[451]:
0            Agassi, Andre
1             Bonds, Barry
2    Columbus, Christopher
3            Defoe, Daniel
4          Estevez, Emilio
5         Flintstone, Fred
6             Garbo, Greta
7         Humbert, Humbert
8              Ilych, Ivan
dtype: object

In [452]: names.apply(lambda x: ', '.join(x.split()[::-1]))
Out[452]:
0            Agassi, Andre
1             Bonds, Barry
2    Columbus, Christopher
3            Defoe, Daniel
4          Estevez, Emilio
5         Flintstone, Fred
6             Garbo, Greta
7         Humbert, Humbert
8              Ilych, Ivan
