Python:Elif 和 Else 不工作

Question

我正在使用 Python 为终端构建一个交互式时间表，但在我的代码末尾，我有 if、elif 和 else 语句，无论我给出什么用户输入，它都会继续传递 if 语句。任何解决方案将不胜感激，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"

且始终为 True。您可以这样解决您的问题:

answer in ["Yes", "yes"]
