我在为AP Computer Science校长项目制作的基于文本的游戏时遇到问题。应该发生的是以下代码行：
def pI(options):
#PI stands for Player Input
playerInput = (input("==> "))
if playerInput not in options or commands:
print(playerInput + " is not a possible option")
print("Do /options for a list of acceptable options")
playerInput = (input("==> "))
if playerInput == "/commands":
print(commands)
elif playerInput == "/options":
print("Acceptable inouts are" + options)
elif playerInput == "/help":
gHelp()
return(playerInput)
应该检查玩家的输入是否可以完成。但是，使用此系统，解释器甚至不会检查playerInput。我没有收到任何错误，但是没有按照我想要的方式工作。逻辑对我来说很有意义，但对解释器却没有意义。有人知道为什么是这样吗？如果有帮助，这里是我到目前为止用于游戏的其余代码：

if playerInput not in options or commands:

playerInput = (input("==> "))
if playerInput == "/commands":

答案 0 :(得分：2)
这里有几个问题：
if playerInput not in options or commands:
如果playerInput不在选项中，或者定义了命令，它将激活。您的意思是说，如果playerInput不在选项中并且playerInput不在命令中，则应该激活它。
pI(options)
if pI == 1:
dream0()
pCS = dream0()
if pI == 2:
load
if PI == 3:
gExit()
if PI == 4:
gHelp()
在这里，您希望pI（options）返回一些值，但是您从不保存它。当您检查pI == 1时，您正在检查函数是否等于1，这是没有意义的。此外，pI返回一个字符串，而不是数字。相反，您应该具有以下条件：
playerInput = pI(options)
if playerInput == "1":
dream0()
pCS = dream0()
if playerInput == "2":
load
if playerInput == "3":
gExit()
if playerInput == "4":
gHelp()
