Here's a good function header given the following:
I wrote the below code

    if (not settings.FEATURES.get('ENABLE_FEEDBACK_SUBMISSION', False)):
        raise Http404()
    if (request.method != 'POST'):
        return HttpResponseNotAllowed(['POST'])
    def build_error_response(status_code, field, err_msg):
        return HttpResponse(json.dumps({'field': field, 'error': err_msg}), status=status_code)
    required_fields = ['subject', 'details']
    if (not request.user.is_authenticated()):
        required_fields += ['name', 'email']
    required_field_errs = {'subject': 'Please    provide    a    subject.', 'details': 'Please    provide    details.', 'name': 'Please    provide    your    name.', 'email': 'Please    provide    a    valid    e-mail.'}
    for field in required_fields:
        if ((field not in request.POST) or (not request.POST[field])):
            return build_error_response(400, field, required_field_errs[field])
    if (not request.user.is_authenticated()):
        try:
            validate_email(request.POST['email'])
        except ValidationError:
            return build_error_response(400, 'email', required_field_errs['email'])
    success = False
    context = get_feedback_form_context(request)
    enterprise_learner_data = enterprise_api.get_enterprise_learner_data(site=request.site, user=request.user)
    if enterprise_learner_data:
        context['tags']['learner_type'] = 'enterprise_learner'
    support_backend = configuration_helpers.get_value('CONTACT_FORM_SUBMISSION_BACKEND', SUPPORT_BACKEND_ZENDESK)
    if (support_backend == SUPPORT_BACKEND_EMAIL):
        try:
            send_mail(subject=render_to_string('emails/contact_us_feedback_email_subject.txt', context), message=render_to_string('emails/contact_us_feedback_email_body.txt', context), from_email=context['support_email'], recipient_list=[context['support_email']], fail_silently=False)
            success = True
        except SMTPException:
            log.exception('Error    sending    feedback    to    contact_us    email    address.')
            success = False
    else:
       ...

What's a good function header?
