Hi Ahmed, When an error happens in an expect: block, python 3 shows the original error caught by the try/expect block, as well as the new error. In this case, the ImportError is the original error, and it's nothing you should worry about: Django catches it and handles it accordingly. Admittedly, the error is slightly confusing. The ImportError has nothing to do with timezones or pytz.
The real error is the second one, the MultipleObjectsReturned exception. Question.objects.get() expects that exactly one object is returned by the database. If there are no objects returned, or more than one is returned, it will raise an expection. If you want to get all objects published in the current year, you can use Question.objects.filter(put_date__year=current_year) instead.
