How to retract Rules in pyDatalog?

[Farhad Shakerin]

Hi there,

Thankyou to the team  behind pyDatalog. It is such a convenient integration of Prolog engine inside python. 

I'm trying to implement a FOIL-like algorithm that needs to dynamically assert and retract different rules.

I was wondering if there was a way to do this without calling clear() function and loading the entire data each time?

I greatly appreciate your help

Best,

Farhad
