从今天到给定日期还有多少天

Question

我有约会 - 2015.05.20

使用python计算从今天到此日期剩余天数的最佳方法是什么？

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

Answer 1

diff = future - today
print diff.days

diff是timedelta个对象。

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
