In my python script I want to save the time like this:
start_time = datetime.now()
How can I make this start_time that it shows me how much seconds , minutes I have , I mean it's possible to do a total_seconds() or something?=
I want to convert this : datetime.now() in seconds only.

If you want the difference between two datetime objects, you can subtract them to get a timedelta object that has a total_seconds() method:
$ python
Python 3.4.3 (default, Oct 14 2015, 20:28:29)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> import time
>>> now1 = datetime.datetime.now()
>>> time.sleep(10)
>>> now2 = datetime.datetime.now()
>>> (now2 - now1).total_seconds()
16.014057
>>>
Using this answer from StackOverflow, you can get the seconds since the epoch (1 Jan 1970):
>>> epoch = datetime.datetime.utcfromtimestamp(0)
>>> seconds_since_epoch = (datetime.datetime.now() - epoch).total_seconds()
>>> seconds_since_epoch
1467410206.475112

23,559 PointsIt's not entirely clear in your question what you're trying to do. Could you possibly rephrase or elaborate a bit?
