How to work with query set in Django?

Question

Django

I have a problem with query set processing.
I have a similar code:

def index(request):
    results = ResultInput.objects.all()
    return render(request, 'main/index.html', {'title': 'Main page', 'results': results})

I would like to implement

n = 0
ihst = []
while len(results) != n:
     ihst.append((results[n].time * 100) / (results[n].f1+results[n].f2+results[n].f3)*2)
     n += 1
print(ihst)

Accordingly, it would be desirable not to do it through while. I wrote this here because it works. How to interact with the query set in general? As I understand it, this is not an iterable object and it will not work to access through for in.

and let's start reading the docks https://docs.djangoproject.com/en/3.1/ref/models/q... so you don't write such nonsense anymore
