You can fix your code by changing datetime.timedelta to timedelta:
*def* was_published_recently(self):
return self.pub_date >= timezone.now() - timedelta(days=1)
The statement "from datetime import datetime, timedelta" imports the
classes datetime and timedelta from the module datetime.
If you prefer to use "datetime.timedelta", you would have to use "import
datetime" instead of "from datetime import datetime, timedelta"
Hope that helps,
Daniel
