python根据出生日期计算年龄的代码详解编程语言

python根据出生日期计算年龄的代码，运行后会提醒用户输出出生的年月日，然后输出年龄，可以改写为一个通用函数

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) 
      
age()
