Python：Elif和Else无法正常工作

Question

我正在用Python构建终端的交互式时间表，但是在我的代码末尾，如果我有if，elif和else语句，无论用户输入什么，我都会传递if声明。任何解决方案将是极大的赞赏，并感谢您的时间:)

while True: 
    TimeTable() 
    print "\nDo you wish to go again? " 
    answer = raw_input() 
    if answer == "Yes" or "yes": 
     print " " 
     continue 
    elif answer == "No" or "no": 
     print "Ok then" 
     break 
    else: 
     print "Ok then" 
     break 

Answer 1

answer == "Yes" or "yes" 

# is the same as 
(answer == "Yes") or "yes" 

而且总是如此。你能解决你的问题是这样的：

answer in ["Yes", "yes"]
