Exploring dbase with python script

Hi all,
I've got a question and hope someone can help me.

I've got two dbase (.dbf) which are looking like this:
dbase 1:
ID usage shape_area
1 living 50

dbase 2:
ID usage shape_area
1 living 50
2 farming 25

Now I want to write a python script, which can explore the dbase. Output should be something like "The difference between dbase1 and dbase2 is an object with the ID 2.
That means, that I need something to count the objects in both dbase-files and to compare the objects. Is it possible to realize this with python?

Thank you for answering.
