How to compare two dates?
Use the datetime
method and the operator <
and its kin.
>>> from datetime import datetime, timedelta>>> past = datetime.now() - timedelta(days=1)>>> present = datetime.now()>>> past < presentTrue>>> datetime(3000, 1, 1) < presentFalse>>> present - datetime(2000, 4, 4)datetime.timedelta(4242, 75703, 762105)
Use time
Let's say you have the initial dates as strings like these:date1 = "31/12/2015"
date2 = "01/01/2016"
You can do the following:newdate1 = time.strptime(date1, "%d/%m/%Y")
and newdate2 = time.strptime(date2, "%d/%m/%Y")
to convert them to python's date format. Then, the comparison is obvious:newdate1 > newdate2
will return False
newdate1 < newdate2
will return True
