looking for exercice or more code source example for pydatalog use

[buffalo]

hello,
i need more to understand how to use properly pydatalog. I am very intersted in, but debuging is not easy for me.

I dream on a compilation of exercice and full programms with pydatalog . Not just short snippets. I want to get the big picture.

If you are at very begining level, you just cannot not acces stackoverflow due to savage downvote.

Yeh, i can not format properly my questions because i am at very low comprehension level.

I can just read other people questions and it is not enought.

I had a look on nullege, stack, google. Just little piece of the big puzzle.

 Why not a sketch with what,when, syntax, inclusion with python... ?
