In Python 2/3:

For display, I would like to convert the `datetime` instance retrieved from the database to local `datetime` using the default local timezone (i.e., as if the `datetime` was created using `datetime.now()`).

] | You can't do it with standard library. Using **pytz** module you can convert any naive/aware datetime object to any other time zone. Lets see some examples using Python 3.

The [documentation for the tzinfo class](http://docs.python.org/library/datetime.html#tzinfo-objects) does come with some useful examples. Look for the large ... |
