33.1.1. Write a program to calculate the number of days elapsed since the birthday.
from datetime import datetime
def dayCount(dob,date):
a = datetime.strptime(dob,'%d%m%Y')
b = datetime.strptime(date,'%d%m%Y')
return(b-a).days
dob = input("dob in ddmmyyyy format: ")
dd = int(dob[:2])
mm = int(dob[2:4])
yy = int(dob[4:])
todaysDate = input("today's date in ddmmyyyy format: ")
dd1 = int(todaysDate[:2])
mm1 = int(todaysDate[2:4])
yy1 = int(todaysDate[4:])
print("days since birthday:", dayCount(dob,todaysDate))
