It works fine here. I entered your commands exactly and the second one does not
provide any output.
What shell do you have? And what version of Python and Django? And what OS?

Yes I agree. But why does it complain that datetime doesn't exist when I do "
./manage.py shell < test " ?
Shouldn't it also not do anything like when I paste into a Python3 or Django
shell as you did?

$ python3
Python 3.8.10 (v3.8.10:3d8993a744, May 3 2021, 08:55:58)
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime ; [datetime for e in [1, 2]]
[<module 'datetime' from
'/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/datetime.py'>,
<module 'datetime' from
'/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/datetime.py'>]
It does not do anything.
