shuffle什么意思？
除了翻译成“拖曳摇摆地走;搅乱;推诿,推卸”，还有洗牌的意思，随机但不重复。
Shuffle?the cards and deal out five?to each?player.
Python random 模块除了有以下常用的函数外：
random()? ? ? ? ? ?返回0<=n<1之间的随机实数n；
choice(seq)? ? ? ?从序列seq中返回随机的元素；
getrandbits(n)? ?以长整型形式返回n个随机位；
sample(seq, n)? 从序列seq中选择n个随机且独立的元素。
还有一个“随机发牌”函数： shuffle()：
>>> from random import shuffle
>>> n = [2, 3, 4, 5, 6, 7, 8, 9]
>>> shuffle(n)
>>> n
[7, 5, 6, 2, 4, 9, 3, 8]
>>> shuffle(n)
>>> n
[4, 6, 2, 3, 7, 8, 5, 9]
>>> 直接随机打乱原序列的顺序排列，刚好可以用它来模拟发牌。
一副扑克牌54张，四种花色，每种13张，另加大小王各一张。
三人斗地主用一副，掼蛋则是四人用两副牌，每人27张牌。
扑克牌表示如下（其中10用字母T来表示）：
>>> F = ('?', '?', '?', '?')
>>> V = tuple(str(i) for i in range(2,10))+('T','J','Q','K','A')
>>> V
('2', '3', '4', '5', '6', '7', '8', '9', 'T', 'J', 'Q', 'K', 'A')
>>> 大小王分别用 Rj, Bj 表示：
>>> P = [f+v for f in F for v in V] + ['Rj','Bj']
>>> P
