We were given a hint to calculate the number of pets the owner has with these function:

def has_multiple_pets(self):
    return self.patient_set.count()>1

My understanding is that the patient_set represents a list/queryset of patients that reference the Owner model. How accurate is that? Why is it so weirdly put? Don’t get me wrong, I love that there’s a way to reference other sets but the syntax is weird. It starts with a small letter for example and it has “set” appended to it.
