Sure, how you would normally update a value. Assuming id is unique:

id2 = ExampleTable.objects.get(id=2)

id2.example_list

You now have the example_list and you can do what you want with it. What
that is depends on what field type you have declared example_list in
your model? That is why I suggested the jsonfield in a previous post, it
automatically converts Python data structures into JSON and the reverse.

Then:

id2.save()

In your Django project I would crank up:

python manage.py shell

and work with the model directly to see what is happening.
