if, elif & !=, == 布尔运算仅在输入时返回“false”

Question

我正在创建一个“我们之中”的盗版（为了好玩！），而 while True 和 if/elif/else 语句只会返回 false（不是冒名顶替者）的输入。我创建了一个姓名列表，列表中的 2 个随机元素将被选为An Impostor。但是，每当我输入The Impostor的名称时，它只会返回（玩家）不是冒名顶替者。这是我的代码；import sys, time, randomnames = ["player1", "player2", "player3", "player4", "player5", "player6", "player7", "player8", "player9", "player10"]print("Players: ")for x in names:  print(x)print('—————————————————————————')impostor1 = random.choice(names)impostor2 = random.choice(names)crewmates = 8impostors = 2tries = 6while True:  talk = input("Guess who The Impostor(s) are. " + str(crewmates) + " Crewmates are left. " + str(impostors) + " Impostors are left. You have " + str(tries) + " tries left.")  if talk in names:    print(talk + " was voted for.")    time.sleep(0.1)    if talk != impostor1 or talk != impostor2:      notimp = talk + " was not An Impostor. "      names.remove(talk)      for y in notimp:        sys.stdout.write(y)        sys.stdout.flush()        time.sleep(0.05)      crewmates -= 1      tries -= 1    elif talk == impostor1 or talk == impostor2:      wasimp = talk + " was An Impostor. "      names.remove(talk)      for v in wasimp:        sys.stdout.write(v)        sys.stdout.flush()        time.sleep(0.1)      impostors -= 1  else:    print("That player was either ejected or is not a valid player.")但是，每当我将冒名顶替者放入输入中时，它都会说它不是冒名顶替者？

我认为这一行是问题的根源：

if talk != impostor1 or talk != impostor2:

假设impostor1isplayer1 和impostor2isplayer2 以及inputplayer1中的某个人，根据PythonBoolean表达式运算符，or该if语句的计算结果如下：

if player1 != impostor1评估为False因为player1 确实等于impostor1。

到目前为止一切顺利，但由于第一个测试是False，Python 只是计算并返回右侧操作数，该操作数可能是True或False。在你的情况下，Python 将评估if talk != impostor2并返回True，然后执行嵌套块。
