Python - if语句无法正常工作

Question

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.

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,即使我回答否定答案,它仍然会回复一个回复,好像我说的是,如果我切换2(所以否定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.

Answer 1

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

要么

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

会做的
