How to extract hours and minutes from a datetime.datetime object?

问题

I am required to extract the time of the day from the datetime.datetime object returned by the created_at attribute. But I do not understand how to do that. This is my code for getting the datetime.datetime object.

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

I need to only extract the hour and minutes from t1.

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

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

for example.

回答2:

If the time is 11:03, then the accepted 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]

回答3:

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

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

回答4:

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.
