class relate(models.Model):
_name = 'relate'
_rec_name = 'car'

@api.multi
@api.onchange('start', 'end', 'ignore')
def years_rang(self):
    for rec in self.search([]):
        if not rec.rang:
            record = [int(x) for x in range(int(rec.start), int(rec.end) + 1)]
            list = []
            if rec.ignore:
                try:
                    record.remove(int(self.ignore))
                    list= []
                    print(record)
                except ValueError:
                    return {'warning': {'title': 'Warning!', 'message': "the Ignored year doesn't in range"}}
                else:
                    for item in record:
                        range_id = self.env['yearrange'].create({'name': str(item)})
                        list.append(range_id.id)
                    rec.rang = [(4, x, None) for x in list]
        else:
            return

start = fields.Char(string="", required=False, )
end = fields.Char(string="", required=False, )
rang = fields.One2many(comodel_name="yearrange", inverse_name="product_id", store=True, string="Years" ,)
ignore = fields.Char(string="Ignore", required=False, )

class yearrange(models.Model):
_name = 'yearrange'
_rec_name = 'name'

name = fields.Char()
product_id = fields.Many2one(comodel_name="relate"

any kind of help will be appreciated

May be below code is not allowing to move ahead and gives exit from loop :
