Python Gets the timestamp of the 0 o'clock in the morning of the day __python

Recently wrote Python, encountered a problem, need to get the day 0 o'clock in the morning time stamp, the internet really did not find, I handwritten a, a bit of a setback

#-*-Coding:utf-8-*-
import time

now_time = Int (Time.time ())
day_time = now_time-now_time% 86400 + time.t Imezone
day_time_str = Time.asctime (Time.localtime (day_time))
print day_time
print day_time_str

Import datetime Today
= Datetime.date.today ()
today_time = Int (time.mktime today.timetuple ())
print Today_time

The output is as follows:

1518105600
