Read time and date from a text file

[huisky]

Hi,

As a newbie, I posted my question here again.
say i have two dics read from a text file by 'split'.

>>> cstart

defaultdict(<type 'int'>, {15424: ['Dec', '6', '18:57:40'], 552:
['Dec', '7', '09:31:00'], 15500: ['Dec', '6', '20:17:02'], 18863:
['Dec', '7', '13:14:47'], 18291: ['Dec', '6', '21:01:17'], 18969:
['Dec', '7', '14:28:42'], 18937: ['Dec', '7', '14:21:34']})
>>> ccompl

defaultdict(<type 'int'>, {15424: ['Dec', '6', '19:42:55'], 18291:
['Dec', '6', '21:01:28'], 15500: ['Dec', '6', '20:26:03'], 18863:
['Dec', '7', '13:24:07']})

and I need to calculate the difference time if the key value is the
same in both dics.

Someone suggested me to use the module 'datetime', but I'm still
wondering how to make it work.
I mean how to assign ['Dec','6','21:01:17'] to a 'datetime' object and
then do the datetime operation.
>>>time=datetime.datetime(cstart[18291])       does NOT work.

thanks in advance
