How to get Flask to save user input for radio button?

Question

So I am trying to create an interactive quiz application using Flask. However, the issue I am running into is that I can't seem to save and output what the user selected. I tried to fix the quiz_answers function in the app.py and the quiz_solutions.html jinja2 syntax, but got an output that I did not want.

Example Question: What is 2+2?

Multiple choice: Option 1: 4, Option 2: 5, Option 3: 6, etc.

What I want the html page to show:

User selected: Option 2: 5
Correct Answer: Option 1: 4

Here is a what I currently have for app.py:

from flask import Flask, render_template, request
import random, copy
import questions
app = Flask(__name__)

copy_questions = copy.deepcopy(questions.original_questions)

def shuffle(q):
 """
 This function is for shuffling 
 the dictionary elements.
 """
 selected_keys = []
 i = 0
 while i < len(q):
  current_selection = random.choice(list(q.keys()))
  #current_selection = list(q.keys())
  if current_selection not in selected_keys:
   selected_keys.append(current_selection)
   i = i+1
 return selected_keys

questions_shuffled = shuffle(copy_questions)

@app.route('/')
def quiz():
 #questions_shuffled = shuffle(copy_questions)
 for i in copy_questions.keys():
  random.shuffle(copy_questions[i])
 return render_template('main.html', q = questions_shuffled, o = copy_questions)

@app.route('/solution', methods=['POST'])
def quiz_answers():
  for i in copy_questions.keys():
    answered = request.form[i]
    if questions.original_questions[i][0] == answered:
      return render_template('quiz_solutions.html',q = questions_shuffled, o = copy_questions)
    break


if __name__ == '__main__':
 app.run(debug=True)

questions.py:

original_questions = {
'What is 2+2': ['Option 1: 4', 'Option 2: 5', 'Option 3: 6',' etc.']
}

main.html:

<h1>Math Quiz</h1>
<form action='/solution' method='POST'>
<!--<form action='/' method='POST'>-->
    <ol>
        {% for i in q %}
            <li>{{i}}</li>
            {% for j in o[i] %}
                <input type='radio' value='{{j}}' name='{{i}}' />{{j}}
                <br>
            {% endfor %}
            <br>
        {% endfor %}
        <br>
        <input type="submit" value="Submit" />
    </ol>
</form>

quiz_solutions.html:

<h1>Math Quiz</h1>
<form method='POST'>
    <ol>
        {% for i in q %}
            <li>{{i}}</li>
            {% for j in o[i] %}
                <input type='radio' value='{{j}}' name='{{i}}' />{{j}}
                <br>
            {% endfor %}
            {% for j in o[i] %}
                {% if j== o[i][0] %}
                    Correct answer: {{j}}
                {% else %}
                {% endif %}
            {% endfor %}
            <br>
        {% endfor %}
    </ol>
</form>
