Python“；或；语句语法不起作用？

我对python编程比较陌生，无论如何，这是一段较大代码的一小部分。这似乎引起了一些问题：

command = input("Command: ")

while command != ("Exit lift" or "Up" or "Down" or "1" or "2" or "3" or "Cycle"):
    print("Error: Command entered doesn't match the 'Commands' list, or isn't a possible command at this time! Please try again...")
    command = input("Command: ")

print ("Works")

基本上，我测试了这些命令，它只接收“退出提升”命令和“向上”、“向下”、“1”等。不行

有什么建议吗？初学者

（“退出提升”或“上升”或“下降”或“1”或“2”或“3”或“循环”）

评估为

退出提升“

>>> ("Exit lift" or "Up" or "Down" or "1" or "2" or "3" or "Cycle")
'Exit lift'

所以

命令！=（“退出提升”或“上升”或“下降”或“1”或“2”或“3”或“循环”）：

相当于

命令！=（“出口电梯”）

按顺序使用

不在
中：

while command not in ("Exit lift", "Up", "Down", "1", "2", "3", "Cycle"):
    ....

（“退出提升”或“上升”或“下降”或“1”或“2”或“3”或“循环”）
计算为
“退出提升”

>>> ("Exit lift" or "Up" or "Down" or "1" or "2" or "3" or "Cycle")
'Exit lift'

所以
命令！=（“退出提升”或“上升”或“下降”或“1”或“2”或“3”或“循环”）：
相当于
命令！=（“出口电梯”）

按顺序使用
不在
中：

while command not in ("Exit lift", "Up", "Down", "1", "2", "3", "Cycle"):
    ....

而不是

while command != ("Exit lift" or "Up" or "Down" or "1" or "2" or "3" or "Cycle"):

你应该使用

while not command in ("Exit lift", "Up", "Down", "1", "2", "3", "Cycle"):

而不是

while command != ("Exit lift" or "Up" or "Down" or "1" or "2" or "3" or "Cycle"):

你应该使用

while not command in ("Exit lift", "Up", "Down", "1", "2", "3", "Cycle"):

您可以使用数组，并在
单词中使用

allowed = ["Exit lift", "Up", "Down", "1", "2", "3", "Cycle"]

while command not in allowed:
    print "not allowed!"

print "works"

您可以使用数组，并在
单词中使用

allowed = ["Exit lift", "Up", "Down", "1", "2", "3", "Cycle"]

while command not in allowed:
    print "not allowed!"

print "works"
