python - Python 2.7:如果代码块不起作用

我已经测试了下面的程序，没有错误。但每当我输入"hangman"时，它都不会启动名为if的新"if response_2"语句块。为什么它不运行它？

    response_2 = raw_input("What would you like to play? Hangman or Word Guess?")
    if response_2 == ("Hangman", "hangman"):
        print "Running Hangman..."
        print "Catching Criminals..."
        print "Building Gallows..."
        print "Getting that one song boy from Pirate's of the Carribean"
    elif response_2 == ("Word_Guess", "word_guess", "word guess", "Word Guess", "Word guess", "word Guess", "Word_guess", "word_Guess"):
        print "Not completed yet"

最佳答案

这是因为您正直接与带有==的元组进行比较，后者总是给出False，因为raw_input给出的是字符串，而不是tuple。您需要检查序列中是否有任何响应。使用in执行此操作：

if response in ('Hangman', 'hangman'):

与elif中的类似比较类似。
