Go to Chapter 22 in A Smarter Way.

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)

Exercises

See http://www.asmarterwaytolearn.com/python/22.html

  1. 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!
  2. Now use the nested for-loops to populate the empty list.
  3. Print your list of friends. Don’t forget to properly format the strings.
