Age from birthdate in python
问题内容：
How can I find an age in python from today’s date and a persons birthdate? The
birthdate is a from a DateField in a Django model.
问题答案：
That can be done much simpler considering that int(True) is 1 and int(False)
is 0:
from datetime import date
def calculate_age(born):
today = date.today()
return today.year - born.year - ((today.month, today.day) < (born.month, born.day))
