如何从 datetime.datetime 对象提取小时和分钟？

我需要从 Ref = “ https://developer.twitter.com/en/docs/twitter-api/v1/data-dictionary/object-model/tweet”rel = “ noReferrer”> create _ at 属性返回的 Datetime.datetime对象中提取一天中的时间，但是我怎么做呢？

这是获取 datetime.datetime 对象的代码。

from datetime import *
import tweepy


consumer_key = ''
consumer_secret = ''
access_token = ''
access_secret = ''
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_secret)
api = tweepy.API(auth)
tweets = tweepy.Cursor(api.home_timeline).items(limit = 2)
t1 = datetime.strptime('Wed Jun 01 12:53:42 +0000 2011', '%a %b %d %H:%M:%S +0000 %Y')
for tweet in tweets:
print (tweet.created_at - t1)
t1 = tweet.created_at

我只需要从 t1中提取小时和分钟。

I don't know how you want to format it, but you can do:

print("Created at %s:%s" % (t1.hour, t1.minute))

for example.

datetime has fields hour and minute. So to get the hours and minutes, you would use t1.hour and t1.minute.

However, when you subtract two datetimes, the result is a timedelta, which only has the days and seconds fields. So you'll need to divide and multiply as necessary to get the numbers you need.

If the time is 11:03, then afrendeiro's answer will print 11:3.

You could zero-pad the minutes:

"Created at {:d}:{:02d}".format(tdate.hour, tdate.minute)

Or go another way and use tdate.time() and only take the hour/minute part:

str(tdate.time())[0:5]

It's easier to use the timestamp for these things since Tweepy gets both:

import datetime
print(datetime.datetime.fromtimestamp(int(t1)).strftime('%H:%M'))

import datetime
    

YEAR        = datetime.date.today().year     # the current year
MONTH       = datetime.date.today().month    # the current month
DATE        = datetime.date.today().day      # the current day
HOUR        = datetime.datetime.now().hour   # the current hour
MINUTE      = datetime.datetime.now().minute # the current minute
SECONDS     = datetime.datetime.now().second #the current second
    

print(YEAR, MONTH, DATE, HOUR, MINUTE, SECONDS)
