Python - 如何计算自X日期以来经过的时间？
我有一个包含文章的数据库表，每一篇文章都有提交日期。我需要计算自文章在数据库中发布以来的天数和小时数，例如：
This article has been published 4 hours ago.
This article has been published 3 days and 4 hours ago.
已经有一些代码可以重复使用来执行此操作？我在谷歌上搜索过，但也许我没有使用正确的词。
有什么线索可以帮助我吗？
此致，
I have a database table with articles and each one of this articles have a submitted date. I need to calculate the days and hours since the article have been published in the database, like:
This article has been published 4 hours ago.
This article has been published 3 days and 4 hours ago.
There are already some code that I can reuse to do this? I've searched on google, but maybe I'm not using the correct words.
Any clue that could help me?
Best Regards,

看看
datetime包，它拥有您想要的一切需要。当您从一个日期时间减去另一个日期时间时，您会得到一个
timedelta对象。您可以使用total_seconds() 获取以秒为单位的持续时间，并使用除法将其转换为小时和天。那么你唯一的工作就是将其格式化为可读的字符串。Have a look at the
datetimepackage, it has everything you need.when you subtract one datetime from another, you get a
timedeltaobject. You can usetotal_seconds()to get the duration in seconds and use division to convert it to hours and days. Then your only job then is to format it into a readable string.我会将提交的日期转换为
datetime，然后使用类似 https:// gist.github.com/207624 将日期时间转换为人性化字符串。I'd convert the submitted date into a
datetime, then use something like https://gist.github.com/207624 to convert thedatetimeto a humanized string.
