Using SageMath I'm trying to implement a method for the solution of a problem where I in an iterative way add a set of constraints, try to solve the problem to check if exist a solution, if not i remove the constraints and restart.

 except RuntimeError:

Given a set of constraint that I add, how to get their indexes so that I can remove them?

The constraints should be in the order you entered them. To remove the last just do

sage: p.remove_constraint(p.number_of_constraints() - 1)
