Python - if语句无法正常工作 [英] Python - if statement not working correctly

问题描述

我刚刚开始使用python并且已经陷入了一些在我看来显然应该工作的东西。这是我的第一个代码，我只是尝试与用户进行对话。

I've just started using python and have got stuck on something that, in my mind, clearly should work. This is my first code and I just try to have a conversation with the user.

year = input("What year are you in school? ")
yearlikedislike = input("Do you like it at school? ")
if (yearlikedislike == "yes" or "Yes" or "YES" or "yep" or "yup" or "Yep" or "Yup"):
    print("What's so good about year " + year, "? ")
    input("")     
    print("That's good!")
    time.sleep(1)
    endinput = input("I have to go now. See you later! ")
    exit()
if (yearlikedislike == "no" or "No" or "nope" or "Nope" or "NOPE"):
    print("What's so bad about year " + year, "?")
    input("")
    time.sleep(1)
    print("Well that's not very good at all")
    time.sleep(1)
    endinput = input("I have to go now. See you later! ")
    time.sleep(1)
    exit()

我的问题是，即使我回答否定回答，它仍然会回复回复，就像回复一样我已经说过是，如果我切换2（因此负面答案的代码高于肯定答案的代码），它总会回复，好像我给出了否定回复。

My problem is that even if I reply with a negative answer it will still reply with a response as if I have said yes and if I switch the 2 around (so the code for the negative answer is above the code for the positive answer) it will always reply as if I have given a negative response.

推荐答案

if yearlikedislike in ("yes", "Yes", "YES", "yep", "yup", "Yep", "Yup"):

或

if yearlikedislike.lower() in ("yes","yep","yup"):

将成功
