How to get a person's age from his date of birth in Odoo?

Question

In my module I have an entity "Person" with two fields "date_of_birth" (Date)  and "age" (Integer). How can I get the age of a Person from the date of birth?

Hi Ernesto:
Make "age" a computed field with the following settings:
Readonly = True
Stored = False
Copied = False
Depends on: date_of_birth
The code for the computation would be
for record in self:
if record.date_of_birth:
today = datetime.date.today()
# Check if the date has passed this year
if today.strftime("%m%d") >= record.date_of_birth.strftime("%m%d"):
record['age'] = today.year - record.date_of_birth.year
else:
record['age'] = today.year - record.date_of_birth.year - 1
else:
record['age

Hi Ernesto:
You can do like this:
from dateutil.relativedelta import relativedelta
age = fields.Integer(string="Age", compute="_calculate_age")
@api.depend(' date_of_birth ')
def _calculate_age(self):
if self. date_of_birth :
d1 = self. date_of_birth
d2 = datetime.date.today()
self.age =  relativedelta(d2, d1).years
