python根據出生日期計算年齡的代碼，運行后會提醒用戶輸出出生的年月日，然后輸出年齡，可以改寫為一個通用函數

from time import *

a function to find your age
def age():
    print "Enter Your Date of Birth"
    d=input("Day:")
    m=input("Month:")
    y=input("Year:")

#get the current time in tuple format
a=gmtime()
#difference in day
dd=a[2]-d
#difference in month
dm=a[1]-m
#difference in year
dy=a[0]-y
#checks if difference in day is negative
if dd<0:
    dd=dd+30
    dm=dm-1
    #checks if difference in month is negative when difference in day is also negative
    if dm<0:
        dm=dm+12
        dy=dy-1
#checks if difference in month is negative when difference in day is positive
if dm<0:
    dm=dm+12
    dy=dy-1
print "Your current age is %s Years %s Months & %s Days"%(dy,dm,dd)
