Timestamp와 datetime

정말 많이 쓰이게 되는 Timestamp다.

from dataetime import datetime
import time 

# Timestamp -> datetime 
timestamp = 1263460958000 
datetimeobj = datetime.fromtimestamp(timestamp*10**-3)

#datetime -> Timestamp
timestamp = time.mktime(datetimeobj.timetuple())

# datetime strptime
date_string = '2015-07-23 18:59:09' 
datetime.strptime('date_string', '%Y-%m-%d %H:%M:%S')

#strftime 참조
now = datetime.now()
now.strftime("%m/%d/%Y, %H:%M:%S")
