python根据出生日期返回年龄的方法

本文实例讲述了python根据出生日期返回年龄的方法。分享给大家供大家参考。具体实现方法如下：

def CalculateAge(self, Date):
   '''Calculates the age and days until next birthday from the given birth date'''
   try:
     Date = Date.split('.')
     BirthDate = datetime.date(int(Date[0]), int(Date[1]), int(Date[2]))
     Today = datetime.date.today()
     if (Today.month > BirthDate.month):
       NextYear = datetime.date(Today.year + 1, BirthDate.month, BirthDate.day)
     elif (Today.month < BirthDate.month):
       NextYear = datetime.date(Today.year, Today.month + (BirthDate.month - Today.month), BirthDate.day)
     elif (Today.month == BirthDate.month):
       if (Today.day > BirthDate.day):
         NextYear = datetime.date(Today.year + 1, BirthDate.month, BirthDate.day)
       elif (Today.day < BirthDate.day):
         NextYear = datetime.date(Today.year, BirthDate.month, Today.day + (BirthDate.day - Today.day))
       elif (Today.day == BirthDate.day):
         NextYear = 0
     Age = Today.year - BirthDate.year
     if NextYear == 0: #if today is the birthday
       return '％d, days until ％d: ％d' ％ (Age, Age+1, 0)
     else:
       DaysLeft = NextYear - Today
       return '％d, days until ％d: ％d' ％ (Age, Age+1, DaysLeft.days)
   except:
     return 'Wrong date format'

使用方法如下：

print CheckDate('2000.05.05')
