Python string swap formatting [duplicate]

Question

I need to swap the list of names which is in the format of FirstName and LastName which in a dataframe one column, using python.

Below is the sample format: ~Adam Smith

The above need to change into ~Smith Adam

Is there any single line function available in python?

Could anyone help on this!!

This is a trivial task. What did you try? Please include your code. — DYZ

Using apply

import pandas as pd
df = pd.DataFrame({"names": ["Adam Smith", "Greg Rogers"]})
df["names"] = df["names"].apply(lambda x: " ".join(reversed(x.split()))) 
print(df)

Output:

         names
0   Smith Adam
1  Rogers Greg
