doctest + sqlobject (TDD)

[petr.jakes.tpc at gmail.com]

Hi,

inspired by the article written by Tarek Ziade in the February 07
issue of the "Linux +" magazine I am experimenting with the doctest
module.

I have two files, "displeje_pokus.py" and "displeje_pokus.txt" (you
can see the simplified contents of the files bellow).

When I run "python displeje_pokus.py" I am getting an error (see
below) which I am not able to eliminate.

thanks for your reply
