Python How to calculate number of days between 2 dates?

Question

I'm having trouble doing this in a clean and simple way in python.
What I'd like to do is having a piece of code that calculates the number of days passed between 2 dates. For example today being the 22nd of december and i want to know how many days i have before the 15th of febuary. There are 55 days difference
(i took this example because it englobes 2 different years an multiple months)
What i made was very messy and dosen't work half the time so i'm kind of embarrassed to show it.
Any help is appreciated.
Thanks in advance

Solution 1

Simpler implementation:

    import datetime

    d1 = datetime.datetime(2013,12,22)
    d2 = datetime.datetime(2014,2,15)
    (d2-d1).days

Solution 2

just create an instance of both the dates and substract them - you'll get timedelta object with a given info.

>>> from datetime import date
>>> by = date(2013, 12, 22)
>>> since = date(2014, 2, 15)
>>> res = since - by
>>> res.days
55

some examples with a variables

>>> variables_tuple = (2013, 12, 22)
>>> by = date(*variables_tuple)
>>> by.year
2013
>>> until_year = 2014
>>> until = date(until_year, 2, 15)

instead of inputing dates directly can thay also be variables in the parentesis? and does it work with leap years?

yes, you can use variables there and yes, it works with a leap years
