How do I get the number 1554 instead of {'age__sum': 1554} when creating my own template tag?

Question

Django

Has own tag

spoiler

@register.simple_tag
def total_age():
    people = Person.objects.all()
    age = people.aggregate(Sum("age"))
    return age

In the html page, the code is: Всего = {% total_age %}
In the browser: Total = {'age__sum': 1554
} in browser: Total = 1554

Answer 1

return age.get('age__sum', 0)
