python - 有没有办法在python中的两个值之间交替

Question

假设我有一个值说Player 1and Player 2。我可以将它们分配给单个变量吗？

print("%s choose this piece" %Player_value)

预期产出

Player 1 choose this value
Player 2 choose this value

如何才能做到这一点！

请帮忙！

Answer 1

>>> import itertools
>>> player = itertools.cycle(['Player 1', 'Player 2'])
>>> print("%s choose this piece" % next(player))
Player 1 choose this piece
>>> print("%s choose this piece" % next(player))
Player 2 choose this piece
>>> print("%s choose this piece" % next(player))
Player 1 choose this piece
...

Answer 2

有几种很好的方法可以进行这种交换。一个简单的方法是使用整数 1 和 2。交换变成：

    Player_value = 3 - Player_value

另一种方法是有一个列表。这对两个人来说太过分了，但允许两个以上。

    Players = [1, 2]
    print("Player %d choose:" % Players[0] )
    Players.append( Players.pop(0) )

Answer 3

创建一个字典，并遍历它。键是玩家名称，值是玩家值。

playerDict = {"Player1":"10","Player2":"20"}
for players in playerDict:print(f"{players} choose this {playerDict[players]}")

输出

Player1 choose this 10
Player2 choose this 20
