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

    def _decorator(func):
        @wraps(func)
        def _wrapped(*args, **_kwargs):
            request = args[0]
            missing_params = (set(required_params) - set(request.POST.keys()))
            if (len(missing_params) > 0):
                msg = u'Missing    POST    parameters:    {missing}'.format(missing=',    '.join(missing_params))
                return HttpResponseBadRequest(msg)
            else:
                return func(request)
        return _wrapped
    return _decorator

What's a good function header?
