How to compare dates only (and not the time) in python

Question

I have 2 datetime objects. One only has the date and the other one has date & time. I want to compare the dates only (and not the time). This is what I have:

d2=datetime.date(d1.year,d1.month,d1.day)
print d2 == d1.date

It prints out false. Any idea why?

Thank you!

Answer 1

d1.date() == d2.date()

From the Python doc:

datetime.date() Return date object with same year, month and day.

Answer 2

Cast your datetime object into a date object first. Once they are of the same type, the comparison will make sense.

if d2.date() == d1.date():
    print "same date" 
else:
    print "different date"

For your case above:-

In [29]: d2
Out[29]: datetime.date(2012, 1, 19)

In [30]: d1
Out[30]: datetime.datetime(2012, 1, 19, 0, 0)

So,

In [31]: print d2 == d1.date()
True

All you needed for your case was to make sure you are executing the date method with the brackets ().
