Question

我是StackOverflow的新手（第一次发帖），也是使用python进行编码的新手。目前通过Udacity注册课程。我很难完成这个课程的项目，并决定来这里看看是否有人可以提供帮助。

该项目是创建一个有4个空白的测验，需要玩家正确回答。要求使用正确答案进行测验打印，但我很难将其正确打印出来。

我的代码如下。非常感谢我能得到的任何帮助或建议。

谢谢！

Answer 1

以下是play_game（）方法的工作版本：

def play_game(quiz, parts_of_speech):
    replaced = []
    i = 0
    quiz = quiz.split()
    for word in quiz:
        replacement = word_in_pos(word, parts_of_speech)
        if replacement is not None:
            user_input = raw_input("Type an answer for: " + replacement + " " )
            guesses = 0
            while user_input != answers[i]:
                guesses = guesses + 1
                if guesses == 5:
                    return "\nGame Over! Better luck next time. \n"
                print "Incorrect, try again \n" + " ".join(replaced) + " " + replacement
                user_input = raw_input("Type an answer for: " + replacement + " ")
            replaced.append(user_input)
            print "Correct \n" + " ".join(replaced)
            i = i + 1
        else:
            replaced.append(word)
    replaced = " ".join(replaced)
    return replaced

主要的变化是延迟修改replaced列表，直到给出正确的答案。这简化了许多代码，无需使用word变量。

这个Python测验让我发疯
