Python日期时间:昨天的所有项目 [英] Python Datetime: All Items From Yesterday

问题描述

在Python中，如果我想检查昨天的所有物品，我会做类似的事情:

In Python, if I wanted to do a check for all items from yesterday would I do something like:

from datetime import datetime, timedelta

if datetime.datetime.today() - timedelta(days=2) < item_to_check < datetime.datetime.today():

这会把昨天的所有物品都拉走吗，这是最好的方法吗?

Would this pull all items from yesterday and is this the best way to do it?

推荐答案

我会尝试更简单的方法;-)

I'd try something easier ;-)

from datetime import date, timedelta

yesterday = date.today() - timedelta(days=1)
if item_to_check.date() == yesterday:
    # yup!

请注意，您的

item_to_check < datetime.datetime.today()

对于在您调用 datetime.datetime.today()的第二秒之前发生的任何项目，

是正确的.我的 date.today()不包括小时，分钟或秒(即，它没有时间"部分).

is true for any item that occurred before the second you called datetime.datetime.today(). My date.today() doesn't include hours, minutes or seconds (i.e., it has no "time" component).
