How can I return a random key value from this list tuple? I'm only concerned with returning 'r', 'p', or 's' from moves.

```
# Snippet

moves = [('r', "rock"), ('p', "paper"), ('s', "scissors")]

view_all(moves):
    print "Player moves:"
    for move in moves:
        print " => ".join((move[0], move[1]))

```
