You have a 1 element tuple with a number. Ig you know anything about
Python, it shouldn't be hard to get that value from the tuple.

Starting from version 1.1 Django supports aggregation[1], so you can just write:
>>> from django.db.models import Max
>>> Client.objects.aggregate(maxid=Max('id'))
{'maxid': 2L}
And you'll get a dictionary with the value you want as a result.
