If it's a simple regex comparison on a field, you may be able to do it
directly in the query:
qs = MyModel.objects.exclude(fieldname__regex=r'^regex')
If you really do need to iterate through and exclude things, a
queryset acts just like a list so you can .pop() items and del() them.
Or better, you can append the items you *do* want to a separate list.
