Converting timestamp to unix date python -

here how timestamp looks -

2015-07-17 06:01:51.066141+00:00 

i'm looking around convert unix date time.

datetime.strptime("2015-07-17 06:01:51.066141+00:00", "%y-%m-%d %h:%m:%s.%f%z").strftime("%s")  valueerror: 'z' bad directive in format '%y-%m-%d %h:%m:%s.%f%z' 

throws error me, because of wrong format being used.

ps: virtualenv on python 2.7

ideas please ?

python 2.7 strptime() not support z directive, either can use python 3.2+ or other 3rd party library dateutil.
