I'm new in using Z3py, and my assignment is to generate counter examples for both solutions (sat and unsat).
Is there any function to generate counterexample for unsat solution?

unsat
means there is no model that satisfies the assertions given. You can only extract a model when the problem issat
. So, to answer your question as you posed it, you cannot create models from anunsat
solution: It just does not exist.A typical approach is to assert the
negation
of the formula you are trying to prove; and if that formula is satisfiable then your original formula is falsifiable; i.e., there is a counter-example for it. Perhaps that's what you are trying to do? That is: If the negation of the formula has a satisfying model, then that model is a counter-example for the original formula. This is how most provers built on top of SMT solvers work, by sending the negation of what they are trying to prove and getting backunsat.
If the prover returns a model, then it is a counter-example.
