Yes, but my point still holds, the code above is buggy/unclear. And documentation supports this:

>>> loc_dt = eastern.localize(datetime(2002, 10, 27, 1, 30, 00))

>>> loc_dt.strftime(fmt) '2002-10-27 01:30:00 EST-0500'

> As you can see, the system has chosen one for you and there is a 50% chance of it being out by one hour.

And the solution, you're right, is to not use the code like above. But the article doesn't mention that at all.
