How to use the carto.analysis.Schedule function in carto

def schedule(self, schedule_id):
        return Schedule(self._context, self.job_id, schedule_id)

def schedule_by_token(self, schedule_token):
        return Schedule(
            self._context, *self._context.ids(schedule_token)
        )

def execution_by_token(self, execution_token):
        # workaround: executions only reachable through
        # schedules ATM
        job_id, schedule_id, execution_id = self.tokens.ids(execution_token)
        schedule = Schedule(self, job_id, schedule_id)
        return schedule.execution(execution_id)

def schedule_by_token(self, schedule_token):
        return Schedule(
            self, *self.tokens.ids(schedule_token)
        )
