两个日期之间的滴滴差异在几年？ [英] Pythonic difference between two dates in years?

问题描述

以下是否有更有效的方法？我想在两个日期之间的差异作为一个单一的标量。欢迎任何建议。

  from datetime import datetime 
 start_date = datetime（2010,4,28,12,33 ）
 end_date = datetime（2010,5,5,23,14）
 difference = end_date  -  start_date 
 difference_in_years =（差异.days +差异。秒/ 86400）/365.2425 
  

解决方案

如果你想要精确的结果，我建议使用 dateutil 库。

 来自dateutil.relativedelta import relativedelta 
 difference_in_years = relativedelta（end_date，start_date）.years 
  

是完整的年份（例如一个人的年龄）。如果你想要分数年份，那么可以添加几个月，几天，几个小时，...达到所需的精度。

Is there a more efficient way of doing this below? I want to have the difference in years between two dates as a single scalar. Any suggestions are welcome.

from datetime import datetime
start_date = datetime(2010,4,28,12,33)
end_date = datetime(2010,5,5,23,14)
difference  = end_date - start_date
difference_in_years = (difference.days + difference.seconds/86400)/365.2425

解决方案

If you want precise results, I recommend using the dateutil library.

from dateutil.relativedelta import relativedelta
difference_in_years = relativedelta(end_date, start_date).years

This is for complete years (e.g. a person's age). If you want fractional years, then add months, days, hours, ... up to the desired precision.
