I have two data sets for age and names: Please answer this using Python

Age: 12, 16,22,18,33

Names: Bob, Jones, Emily, Steve, Joana

1) How do I generate a third list(A and B) where A includes adults over 20 and B= age under 20, by using if/else statements.

2) write some code that allows a person to enter their name and get their age group(a or B) as the returned value
