本文實例講述了python根據出生日期返回年齡的方法。分享給大家供大家參考。具體實現方法如下：

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')

希望本文所述對大家的Python程序設計有所幫助。
