Python: Write a program that lists all ways people can line up for a photo (all permutations of a list of strings). The program will read a list of one word names, then use a recursive function to create and output all possible orderings of those names separated by a comma, one order per line.

When the input is:

Julia Lucas Mia 

then the output is (must match the below ordering):

Julia, Lucas, Mia Julia, Mia, Lucas Lucas, Julia, Mia Lucas, Mia, Julia Mia, Julia, Lucas Mia, Lucas, Julia
