Converting datetime to strptime

I'm pulling a timestamp that looks like this - 2014-02-03T19:24:07Z

I'm trying to calculate the number of days since January 1.

I was able to convert it to datetime using 

yourdate = dateutil.parser.parse(timestamp)

But now I'm trying to parse it and grab individual elements, such as the month & day.

Is there a way to convert it to strptime so I can select each element?

Another way to solve without the dateutil module:

import datetime

# start date for comparision
start = datetime.date(2014, 1, 1)

# timestamp as string
datefmt = "%Y-%m-%dT%H:%M:%SZ"
current = "2014-02-03T19:24:07Z"

# convert timestamp string to date, dropping time
end = datetime.datetime.strptime(current, datefmt).date()

# compare dates and get number of days from timedelta object
days = (end - start).days

This assumes you don't care about time (including timezones).

Just to be a little more complete:

>>> from dateutil.parser import parse
>>> from datetime import datetime
>>> import pytz
>>> d = parse('2014-02-03T19:24:07Z')
>>> other = datetime(year=2014, month=1, day=1, tzinfo=pytz.utc)
>>> (d-other).days
33

You have to make sure the other datetime is timezone aware if you're creating it with datetime as opposed to the datetime you're parsing with dateutil.

if you want to calculate:

import dateutil.parser
yourdate = dateutil.parser.parse('2014-02-03T19:24:07Z')
startdate = dateutil.parser.parse('2014-01-01T00:00:00Z')
print (yourdate - startdate)

There's no need for converting. The resulting datetime.datetime object has all necessary properties which you can access directly. For example:

>>> import dateutil.parser
>>> timestamp="2014-02-03T19:24:07Z"
>>> yourdate = dateutil.parser.parse(timestamp)
>>> yourdate.day
3
>>> yourdate.month
2

See: https://docs.python.org/2/library/datetime.html#datetime-objects

Just access the month, day using year, month, day attributes..

>>> import dateutil.parser
>>> yourdate = dateutil.parser.parse('2014-02-03T19:24:07Z')
>>> yourdate.year
2014
>>> yourdate.month
2
>>> yourdate.day
3
