Try the code that is below:
import datetime
from datetime import date
today = date.today()
person = input("Enter your name: ")
byear = raw_input("Enter the four-digit year you were born: ")
bmonth = raw_input("Enter the month (1-12)you were born: ")
bday = raw_input("Enter the day (1-31) you were born: ")
try:
birthdate = date(int(byear), int(bmonth), int(bday))
dif = (today - birthdate).days
print person + "'s birthday was " + str(dif) + " days ago."
except ValueError:
print "The date you entered is not valid!"
