Django find which form was submitted

I have 3 sets of forms in one template. Only one will be displayed at a given time (the other two are completely hidden):

<form style="display: none;">

All 3 forms are displayed with default values ​​and must be valid even if data has not been entered.

However, I would like to know which one was sent when I check view.py.

In views.py, I have the following:

def submitted(request):

    f1 = formset1(request.POST)
    f2 = formset2(request.POST)
    f3 = formset3(request.POST)

    if f1.is_valid() or f2.is_valid() or f3.is_valid():
        f1.save()
        f2.save()
        f3.save()
        # Do a lot of calculations...

        return render(request, 'submitted.html')

The problem is that I do not want f2 or f3 to be saved if only f1 was submitted (each set of forms has its own submit button). The "# Do many of calculate ..." part is quite extensive, and I don’t want to copy the code again unnecessarily.

How can I use the same view, but save and perform calculations only for the presented set of forms?

request.POST :

'submit-form1' in request.POST # True if Form 1 was submitted
'submit-form2' in request.POST # True if Form 2 was submitted
'submit-form3' in request.POST # True if Form 3 was submitted
