Problem 6
由于每轮都要输出commentary，不适合使用continue，把who = next_player(who)放到if-else语句里了。
def play(strategy0, strategy1, score0=0, score1=0, dice=six_sided,
goal=GOAL_SCORE, say=silence):
"""Simulate a game and return the final scores of both players, with Player
0's score first, and Player 1's score second.
A strategy is a function that takes two total scores as arguments (the
current player's score, and the opponent's score), and returns a number of
dice that the current player will roll this turn.
strategy0: The strategy function for Player 0, who plays first.
strategy1: The strategy function for Player 1, who plays second.
score0: Starting score for Player 0
score1: Starting score for Player 1
dice: A function of zero arguments that simulates a dice roll.
goal: The game ends and someone wins when this score is reached.
say: The commentary function to call at the end of the first turn.

Problem 7
参考announce_lead_changes函数，注意local变量。

increases by more than ever before in the game.

an example for the sake of the doctest

>>> f1 = f0(12, 0)
>>> f2 = f1(12, 9)
