basic python with Django -

-

i'm reading of django docs , i've come across 

    obj, created = person.objects.get_or_create(first_name='john', last_name='lennon',               defaults={'birthday': date(1940, 10, 9)})

i'm still learning python in process. i'm bit confused "obj, created = " part of code. assume both "obj" , "created" perform 

    person.objects.get_or_create(first_name='john', last_name='lennon',               defaults={'birthday': date(1940, 10, 9)})

person.objects.get_or_create returns 2 values, assigned obj , created respectively. obj actual object gotten or created, , created flag tells if created (or gotten).
