ASSIGNMENT using Calendar?

1)  WAP to calculate the total age in year, month, and a day where the date of birth will be entered by the user?

Solution of this program by Shiva Sir:-

from datetime import date

a = date(date.today().year, date.today().month, date.today().day)
b = date(int(input("enter year")), int(input("enter month")), int(input("enter day")))

if(a.month>b.month):
months = a.month - b.month
else:
months = b.month - a.month
years = a.year - b.year
if(a.day>b.day):
days = a.day - b.day
else:
days = b.day - a.day

print('{0} years, {1} months, {2} days'.format(years, months, days))

2)  WAP to display before the day, after day when the user enters a number of days.

3)  WAP to create STOP watch when pressings s then start, p then pause and  e then end?

WAP to calculate total age in year, month, and a day where the date of birth will be entered by the user?

from datetime import date

print("##### Welcome to age calculator ######")
birth_year = int(input("Enter your year of birth: \n"))
birth_month = int(input("Enter your month of birth: \n"))
birth_day = int(input("Enter your day of birth: \n"))

current_year = date.today().year
current_month = date.today().month
current_day = date.today().day

age_year = current_year - birth_year
age_month = abs(current_month-birth_month)
age_day = abs(current_day-birth_day)

print("Your exact age is: ", age_year, "Years", age_month, "months and", age_day, "days")
