How can I get the current time in python

-----------------------------------------
import time
time.asctime()
>>> 'Sat May 21 01:34:38 2016'

import time
gmtime = time.gmtime(time.time())
ftime = '%a %d %b %Y %H:%M:%S GMT'
str = time.strftime(ftime, gmtime)
str
>>> 'Fri 20 May 2016 22:35:40 GMT'

----------------------------------------
import email.utils

email.utils.formatdate()
>>> 'Fri, 20 May 2016 22:37:02 -0000'

email.utils.formatdate(localtime=True)
>>> 'Sat, 21 May 2016 01:36:46 +0300'

email.utils.formatdate(usegmt=True)
>>> 'Fri, 20 May 2016 22:36:57 GMT'

---------------------------------------- 
from datetime import datetime

print datetime.now()
>>> 2016-05-21 01:38:16.661000

print datetime.now().time()
>>> 01:38:27.261000

print datetime.utcnow()
>>> 2016-05-20 22:39:04.538000

​now = datetime.now()
print '{}:{}:{}'.format(now.hour, now.minute, now.second)
>>> 1:40:12
