用Python减去日期 [英] Subtracting Dates With Python

问题描述

我正在开发一个简单的程序，告诉一个人他们还活着多久。

I'm working on a simple program to tell an individual how long they have been alive.

我知道如何获取当前日期并获取他们的生日。唯一的问题是我没有办法减去两个日期，我知道了减去两个日期的方法，但是不幸的是它不包括小时，分钟或秒。

I know how to get the current date, and get their birthday. The only problem is I have no way of subtracting the two, I know a way of subtracting two dates, but unfortunately it does not include hours, minutes, or seconds.

我正在寻找一种方法，该方法可以减去两个日期，然后将差值返回到第二个日期，而不仅仅是日期。

I am looking for a method that can subtract two dates and return the difference down to the second, not merely the day.

推荐答案

from datetime import datetime

birthday = datetime(1988, 2, 19, 12, 0, 0)
diff = datetime.now() - birthday
print diff
# 8954 days, 7:03:45.765329
