How to execute a Python script from the Django shell?

I need to execute a Python script from the Django shell. I tried:

    ./manage.py shell << my_script.py

But it didn't work. It was just waiting for me to write something.

The << part is wrong, use < instead:

    $ ./manage.py shell < myscript.py

You could also do:

    $ ./manage.py shell
    ...
    >>> execfile('myscript.py')

For python3 you would need to use

    >>> exec(open('myscript.py').read())
