从今天到给定日期还剩多少天

Question

我有个约会 - 2015.05.20

使用python计算从今天到这个日期还剩多少天的最佳方法是什么？

from datetime import *
today = date.today()
future = date(2015,05,20)
???

Answer 1

import datetime

today = datetime.date.today()
future = datetime.date(2019,9,20)
diff = future - today
print (diff.days)

diff是一个timedelta对象。

Answer 2

减去它们。

>>> from datetime import *
>>> today = date.today()
>>> future = date(2015,05,20)
>>> str(future - today)
'1326 days, 0:00:00'
>>> (future - today).days
1326
