You can put a for-loop inside another for-loop:

first_names = ["Bill", "Joel", "Jeff", "Jim"]
last_names = ["E-boy", "E-man", "Jefferson", "O'theJungle"]
full_names - [ ]

for a_first_name in first_names:
    for a_last_name in last_names:
        full_names.append(a_first_name + " " + a_last_name)

In your examples.py script, create two lists of friends’ first names and last names, plus the empty list to hold the full name. Be creative!
Now use the nested for-loops to populate the empty list.
Print your list of friends. Don’t forget to properly format the strings.
