Question

我试图为python测验编写一个函数，该函数将根据用户操作在字典中显示下一个键（名为＆＃34; question＆＃34;）。我已经有了检查答案是否正确的功能，但我正在努力争取它然后显示下一个键（问题）。我也给了用户3次尝试解决问题所以下一个问题无法显示，除非a）问题得到解答或b）他们用完了猜测。

我已经玩了for循环和while循环，但我似乎能够做的就是一遍又一遍地重复同样的事情。我应该使用范围参数还是其他什么？

riddles=[]
with open("data/riddles.json") as riddles_file:
    riddles = json.load(riddles_file)

def right_answer(answer, riddle):
    return answer == riddle["answer"]

def next_question(riddles):    
    for riddle in riddles:
        #run the first question. If question correct, run the next question. 

app = Flask(__name__)
app.secret_key = 'some_secret' 

@app.route('/<user>', methods = ['GET', 'POST'])
def quiz(user):

    riddle = riddles[0]
    #hard coded to show first question 

    max_guesses = 3

    counter = 0

    if request.method == "POST":
        answer = request.form.get("answer")

        while counter < max_guesses:
            if right_answer(answer, riddle):
                game_status[user] += 1
                next_question(riddles)
                return render_template("user.html", user=user, score=game_status[user], question=riddle["question"], message = "Correct. Well done!")

            else:
                counter += 1
                guesses_left = max_guesses - counter
                print("answer")
                return render_template("user.html", user=user, score=game_status[user], question=riddle["question"], message = "This is wrong. Try again. Your remaining guesses are:", guesses = guesses_left, answer = answer)

    return render_template("user.html", user=user, score=game_status[user], question=riddle["question"] )

Answer 1

我的方式：测验会有一个riddle_number参数，默认设置为0

def quiz(user, riddle_number=0):

    riddle = riddles[riddle_number]

你的测试时间不好：它只适用于失败。而是创建一个标志

    next_riddle = False
    while not next_riddle:
        if right_answer(answer, riddle):
            next_riddle = True
            [...]

        else:
            guesses_left = max_guesses - counter
            if guesses_left == 0:
                next_riddle = True
            [...]

然后我用riddle_number+1
