Convert the unicode to datetime format

A function returns date and time in unicode format.

 u'2014-03-06T04:38:51Z'

I wish to convert this to date and time format and subtract it with current datetime to get the number of days in between.

Thanks in advance

First you have to convert your string to a datetime.datetime object.

import datetime
then = datetime.datetime.strptime(u'2014-03-06T04:38:51Z', "%Y-%m-%dT%H:%M:%SZ")

then represents itself as datetime.datetime(2014, 3, 6, 4, 38, 51), which looks about right. Then you have to get today's date as a datetime.datetime.

now = datetime.datetime.now()

Finally subtract it from your date (or vice versa - the question didn't make it clear).delta is a datetime.timedelta object that stores increments in days, seconds and microseconds. The latter two are always positive, the first can be negative.

for delta in (now-then, then-now):
    print(delta, "::", delta.days, delta.seconds, delta.microseconds)

This prints out:

-1 day, 20:18:14.250142 :: -1 73094 250142
3:41:45.749858 :: 0 13305 749858

Best try it with a few examples to convince yourself it's correct.

Check string is unicode

>>> import types
>>> type(u'2014-03-06T04:38:51Z') is types.UnicodeType
True

Converting strings to datetime:

>>> import datetime
>>> datetime.datetime.strptime(u'2014-03-06T04:38:51Z', '%Y-%m-%dT%H:%M:%SZ')
datetime.datetime(2014, 3, 6, 4, 38, 51)

Subtract from today to 

>>> import datetime
>>> today = datetime.datetime.today()
>>> yourdate = datetime.datetime.strptime(u'2014-03-06T04:38:51Z', '%Y-%m-%dT%H:%M:%SZ')
>>> difference = today - yourdate
print str(difference)
