Я пытаюсь создать веб-сайт, который получает ответы пользователей в виде переключателей. Я сделал переключатели с циклом for и подумал, что мой код на python тоже сможет получать ответы пользователей с циклом for! Я очень новичок в этом, так что, скорее всего, я сделал что-то маленькое не так.

Я думаю, это может быть потому, что внутри цикла for я поместил request.form[word] и, возможно, запрос.форма не получает параметры, которые я ввел в функцию вычисления? Кроме того, я уже пробовал это, и, похоже, это не имеет никакого значения.

Я включил соответствующие части своего кода на python, файл txt, файл html для тестовой страницы и ошибку, которая отображается на моем экране.

 Over the past month, have you been procrastinating more than ever? 1 for nope, 10 for yes too much! In the last month, how often have you sat down and properly relaxed? Choose 1 for once, and 10 for I relax all the time. Have you eaten more/less in the past month? From one to ten how much have your eating habits changed? Do you have perfectionistic tendencies?

Consider these questions as abnormal things you usually don’t do – like if you usually  procrastinate and know it’s part of your personality, think if you have procrastinated more than usual.

Если вы хотите узнать что-нибудь еще об этом, не стесняйтесь спрашивать! И заранее извиняюсь, если мой код неаккуратен.

Это должно генерировать полезный HTML-код. Затем вы secondtestpage получите элементы, например question0 , со значением 1 для ответа № 1 на вопрос № 0. Добавьте 1 к ним, если хотите.

 lt;form action='/secondtestpage' method='POST'gt;  lt;olgt;  {% for qnum,qtext in enumerate(q) %}  lt;ligt;{{qtext}}lt;/ligt;  lt;labelgt;{% for anum,atext in enumerate(answers) %}  {{atext}} lt;input type='radio' value='{{anum}}' name="question{{qnum}}"/gt;  {% endfor %}lt;/labelgt;  {% endfor %}  lt;input type="submit" value=" Next Page "/gt;  lt;/olgt;  lt;/formgt;
