Bite 93. Rock-paper-scissors and generator's send

Generators are cool right?! Did you know you can send values into a generator by calling its send(value) method? Crazy right?

Let's do a little experiment: complete Rock-paper-scissors below, where player_choice receives the next value via send, if q is entered raise a StopIteration.

So the game would work something like this (see all scenarios in the tests):

>>> from rps import game
>>> game = game()
>>> next(game)
Welcome to Rock Paper Scissors
>>> game.send('rock')
paper beats rock, you lose!
>>> game.send('paper')
paper beats rock, you win!
>>> game.send('rock')
tie!
>>> game.send('q')
Traceback (most recent call last):
...
StopIteration

Pretty cool no? As this is an Advanced Bite we're not giving too much away. Good luck, have fun and keep calm and code in Python!
