I am very new to python and I've run across a small problem that I haven't been able to find an answer to by googling. I am running the following code:

from dateutil import relativedelta as rdelta
def diff_dates(date1, date2):
    return rdelta.relativedelta(date1,date2)

d1 and d2 are two separate dates

years = diff_dates(d2,d1)

print "Years: ", years

The values that get printed out for years are the correct values that I'm expecting. My problem is that I need to access those values and compare against some other values. No matter how I try to access the data I get similar errors:

AttributeError: relativedelta instance has no __call__ method

I need to get the years, months, and days and any help would be greatly appreciated.

The object you get, that you call years, has the whole information inside. That object has as attributes the values you want:

In [12]: d = rdelta.relativedelta(datetime.datetime(1998, 10, 20, 1, 2, 3), datetime.datetime(2001, 5, 3, 3, 4, 5))

In [13]: d
Out[13]: relativedelta(years=-2, months=-6, days=-14, hours=-2, minutes=-2, seconds=-2)

In [14]: d.years
Out[14]: -2

In [15]: d.months
Out[15]: -6
