Convert datetime (e.g. 2016-01-01, 2016-01-11) to integer days (e.g. 0, 11) in Python

Question

Is it possible to convert a timestamp object in the format "2016-01-01" (year month day) into number of days from new years?

I'm getting my timestamp object by str(pandas.to_datetime('today')).split(" ")[0]

I would put code that I used to get it started but I don't even know where to begin except by making a dictionary for how many days are in each month and then calculating it the long way. Is there something built in that I can use for this?

The `datetime.strptime` method and the `timedelta` method would be useful to you — OneCricketeer, Apr 24 '16 at 00:19

@cricket_007 - The second link is useful here, but the OP is starting with a `datetime` and then converting it with `str()` for some reason, so instead of converting that back to `datetime` they can just dispense with `str()` in the first place. — TigerhawkT3, Apr 24 '16 at 00:28
@TigerhawkT3 It wasn't clear what the types were, so I provided both, just in case — OneCricketeer, Apr 24 '16 at 00:31

from datetime import datetime, timedelta, date
import dateutil
st_date = '2016-11-01'
dt = dateutil.parser.parse(st_date).date()
tm_diff = dt - date(2016, 1, 1);
print tm_diff.days

The OP already had a `datetime` object. There's no need to install and import third-party modules for this. – TigerhawkT3 Apr 24 '16 at 00:43
