I wrote the below code

    class Operator(TokenBase, ):
        lbp = bp
        def led(self, left, parser):
            self.first = left
            self.second = parser.expression(bp)
            return self
        def eval(self, context):
            try:
                return func(context, self.first, self.second)
            except Exception:
                return False
    return Operator
