Maybe this other project might be useful for you: https://github.com/ltworf/relational/blob/master/relational/relation.py

Division is already present https://github.com/centaurialpha/pireal/blob/master/src/core/relation.py#L206

Keep in mind that this project basically started as a fork of relational with a different UI.

Only recently it got a reimplemented parser.

@allentiak The idea is that students implement the division operation in terms of the fundamental relational algebra operators.

@usercz That's right, I initially based on the "relational" project but I had to redo the interpreter to support the relational algebra syntax.
