Question

所以基本上我一直在用python创建一个小的叙述选择游戏，它有很多选择，所以它有很多其他选择，但对为什么它们不起作用感到困惑我试图移动东西，但不占上风

print("On the large worktop you see a pot filled with a stew it seems rather fresh")
answer2=input("do you eat it?")
if answer2=="yes" or "Yes" or " yes":
    print("The salty taste of the stew makes you splutter but fills your stomach,You gain 3 hp")
else:
    print("Out of caution you leave the stew on the work top")
answer3=input("As you leave the kitchen the tunnel splits into two do you go right or left?")
if answer3=="left" or "Left":
    print("you head down the left route you hear a slow click spikes rise from the ground and impale your foot you loose 3 hp and slowly limp back to the to the start of the passage and make your way down the right side")
else:
    print("you walk down to the end of the passage way")

Answer 1

您的if语句有问题，因为它们不完整。您要考虑的每个或都必须是完整的逻辑表达式。

if answer2 == "yes" or answer2 == "Yes" or answer2 == " yes":

if answer3 == "left" or answer3 == "Left":

Answer 2

给出了食谱，但我只想阐述一点：

if x == "yes" or " yes "将始终返回True，因为or " yes "基本上是在询问python " yes "是否为None。而且它不是None，因为它是yes。

如上所述，您希望将其更改为以下内容：

if answer == "Yes" or answer == " Yes ":
    ...

我实际上建议您进一步介绍一下：

if "yes" in answer.lower():
   ...

这样，您可以检查答案是否是肯定的（显然，这样做有缺点，以确保您在其他问题中不使用yes），但可以帮助您的代码更易于维护。

Answer 3

在python中使用关系运算符时，请确保在与and和or一起使用时，在运算符的左侧和右侧都存在操作数。

执行类似if answer2=="yes" or "Yes" or " yes":的操作，将始终执行if块中的语句，因为这将始终为true。因此，当用户输入answer2的值而不是“是”或“是”时，if语句中存在的语句将不会执行。

print("On the large worktop you see a pot filled with a stew it seems rather fresh")
answer2=input("do you eat it?")
if answer2 == "yes" or answer2 == "Yes":
    print("The salty taste of the stew makes you splutter but fills your stomach,You gain 3 hp")
else:
    print("Out of caution you leave the stew on the work top")
answer3=input("As you leave the kitchen the tunnel splits into two do you go right or left?")
if answer3 == "left" or answer3 == "Left":
    print("you head down the left route you hear a slow click spikes rise from the ground and impale your foot you loose 3 hp and slowly limp back to the to the start of the passage and make your way down the right side")
else:
    print("you walk down to the end of the passage way")

我已经创建了变量，但是它们都没有起作用
