从今天到现在还有多少天

Question

我有一个日期-2015.05.20

使用python计算从今天到现在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。
