这里有新鲜出炉的Python3 Cookbook中文版，程序狗速度看过来！
Python编程语言
Python 是一种面向对象、解释型计算机程序设计语言，由Guido van Rossum于1989年底发明，第一个公开发行版发行于1991年。Python语法简洁而清晰，具有丰富和强大的类库。它常被昵称为胶水语言，它能够把用其他语言制作的各种模块（尤其是C/C++）很轻松地联结在一起。
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')
