Sorting dictionary by datetime value

[Igor Korot]

Hi, ALL,
I'm trying to do a very easy task: sort python dictionary by value
where value is a datetime object.

When trying to do that in Python shell everthing works as expected.

C:\Documents and Settings\Igor.FORDANWORK>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

a = {}
import datetime
a['1'] = datetime.datetime(2012,12,28,12,15,30,100)
a['2'] = datetime.datetime(2012,12,28,12,17,29,100)
a['3'] = datetime.datetime(2012,12,28,12,16,44,100)
sorted(a.items(), key=a.get)

[('1', datetime.datetime(2012, 12, 28, 12, 15, 30, 100)), ('3', datetime.datetim
e(2012, 12, 28, 12, 16, 44, 100)), ('2', datetime.datetime(2012, 12, 28, 12, 17,
29, 100))]
However, trying to do the same thing from the script does not sort the
dictionary:

sorted(my_dict.items(), key=my_dict.get, reverse=False)
for key, value in my_dict.items():
print value, key

the dictionary prints with unsorted items.

I am trying to run it on Windows XP and the data are coming from the DB.

What am I missing?

Thank you.
