Use values() or values_list().
If you use values(), You’ll end up with a list of dictionaries (technically a ValuesQuerySet)
instance = MyModel.objects.values('description')[0]
description = instance['description']
If you use values_list(), you’ll end up with a list of tuples
instance = MyModel.objects.values_list('description')[0]
description = instance[0]
Or if you’re just getting one value like in this case, you can use the flat=True kwarg with values_list to get a simple list of values
description = MyModel.objects.values_list('description', flat=True)[0]
