如何从datetime.datetime对象中提取小时和分钟？

Question

我需要从created_at属性返回的datetime.datetime对象中提取当天的时间.但我不明白该怎么做.这是我获取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

我只需从t1中提取小时和分钟.

Answer 1

不知道你想如何格式化它,但你可以这样做:

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

例如.

Answer 2

如果时间是11:03,则接受的答案将打印11:3.

您可以将分钟填零:

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

或者采用另一种方式使用tdate.time()并且仅使用小时/分钟部分:

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

Answer 3

由于Tweepy得到了两者,因此使用时间戳更容易

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

Answer 4

datetime有字段hour和minute.所以要获得小时和分钟,你会使用t1.hour和t1.minute.

但是,当您减去两个日期时间时,结果是timedelta,它只包含days和seconds字段.因此,您需要根据需要进行除法和乘法以获得所需的数字.

Answer 5

import datetime

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

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