How to get id ("not name") of a radio button via POST request in django?

  <div class="form-check">
  <input class="form-check-input" type="radio" name="q1" id="q1a">
  <label class="form-check-label" for="q1a">
    A story teller
  </label>
</div>
<div class="form-check">
  <input class="form-check-input" type="radio" name="q1" id="q1b" >
  <label class="form-check-label" for="q1b">
    A problem solver
  </label>
</div>

In the above code the name of the radio button is q1 which I can access by,

sq1 = request.POST.get('q1',"off") in views.py

but, I want to access it specifically by id 

so if I use 

w1a = request.POST.get('q1a',"off") it is giving me no value

HOW CAN I GET IT BY ONLY ID?
