I have this in my front-end (using AlpineJS to go through a loop) :

x-model="rule.protocol"
:name="'protocol[' + rule.pk + ']'"
:value="rule.protocol"
So the print(request.POST) is like this :
<QueryDict: {'csrfmiddlewaretoken': ['xxx'], 'rules[]': ['18580', '18581', '18582', '18583'],
'type[18580]': ['SSH'], 'protocol[18580]': ['TCP'], 'port_range[18580]': ['343434'],
'ip_range[18580]': ['Custom'], 'source_destination[18580]': ['172.16.16.0/24'],
I want request.POST['type[18580]'] as request.POST['type'][18580] and not as a string (‘type[18580]’)
        data['form'] = TestForm()
        if request.method == "POST":
            # request.POST.getlist("array") by using this you can get list of data
            print(request.POST.getlist("array"))
            data['form'] = TestForm(request.POST)
    if request.method == "POST":
        if data['form'].is_valid():
            return redirect('.')
    return render(request, html_path, data)
              
Let me simplify this :
I have a <form> which has 3 input fields :
<input type="text" name="foo[10]" value="a" />
<input type="text" name="foo[22]" value="b" />
<input type="text" name="foo[35]" value="c" />
How do I access it as request.POST['foo'][22] instead of request.POST['foo[22]']
              
I guess I’ll revert to :
<input type="text" name="age" value="a" />
<input type="text" name="age" value="b" />
<input type="text" name="age" value="c" />
and ages= request.POST.getlist('age')
