[Django]-Django and radio buttons

✅

Just filter the POST keys:

for score_key in filter(lambda key:key.startswith('score'), request.POST.keys()):

    total_score += int(request.POST[score_key])

Update

Thinking about it, a list comprehension would be better than filter:

for score_key in [key for key in request.POST.keys() if key.startswith('score[')]:

   total_score += int(request.POST[score_key])

Update 2

Another way that I have been looking into, is keeping the name for each radio button the same (e.g. score) and then merging the quiz id with the value: 

<input type="radio" name="score" value="{{quiz.id}}-{{answer.score}} />

You could then easily get a list of all scores and split the values:

for value in request.POST['score']:
    quiz_id, score = value.split('-')

You are using a PHP-ism by naming the inputs score[{{quiz.id}}]. Don’t do that. Just call them all score, and your browser will do the right thing by putting them all in the same POST value which you can then get via request.POST.getlist('score').
