Python Dates and Times in Python (2014) Where on Earth do Timezones Make Sense? Actually, Use pytz Instead

Correction-localize method works only with naive datetime

Kenneth Love :You mentioned in the video that you believed localize method can take aware datetimes too, however in a codechallenge when I tried to use localize on an aware datetime, it did not work. Further when I tried it an Python EVAL loop I got ValueError saying localize take naive datetime. Request your comments on the same.

Well, looking at the pytz docs, seems I was wrong:

This library only supports two ways of building a localized time. The first is to use the localize() method provided by the pytz library. This is used to localize a naive datetime (datetime with no timezone information)

On a totally unrelated topic, why can't we use del on file objects which we get through open function. For Eg:

file_object = open('file_name')
del file_object

Uh, I can delete a file object just fine. It leaves an unclosed file hanging around, though.
