如何检查两个日期时间是否在一定范围内？ [英] How to check if two datetimes are within a certain range of each other?

问题描述

我有两个datetime64对象a和b，我想确定它们是否在彼此的一定范围内。但是，范围不对称。如果a在b的-30至120分钟之内（a比b早半小时到晚两个小时之间），则两者均在所需范围内。我的日期时间对象看起来像％m /％d /％Y％H：％M。我试着说：

I have two datetime64 objects, a and b, and I want to determine if they are within a certain range of each other. However, the range is not symmetrical. If a is within -30 and 120 minutes of b (a is between half an hour earlier and two hours later than b), the two are within the desired range. My datetime objects look like %m/%d/%Y %H:%M. I tried saying:

difference = a - b
if (-30 <= difference <= 120):
    #Do stuff

但是，这不起作用，因为差异不在几分钟之内。我不确定如何执行此比较。我知道timedelta可以用于日期时间比较，但是我不知道如何在不对称范围内使用它。

However, this doesn't work because difference is not in minutes. I am not sure how to perform this comparison. I know timedelta can be used for datetime comparisons, but I don't know how to use it with an asymmetric range like this one.

谢谢。

推荐答案

比较 timedelta 差异到另外两个 timedelta s：

Compare the timedelta difference to two other timedeltas:

from datetime import timedelta

if timedelta(minutes=-30) <= difference <= timedelta(minutes=120):
