Answer 1

@api.onchange('sem_tot')
def sem_count(self):
    model = self.env['module4_sem'].sudo()
    s_ids = []
    for rec in self:
        rec.sem_no = False
        s = model.search([('id', '<=', rec.sem_tot)])
        s_ids.extend(s.ids)

    return {'domain':{'sem_no': [('id', 'in', s_ids)]}}
