python - 从今天到给定日期还有多少天

Question

我有一个约会 - 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 timedelta对象。
