I am trying to set a conditional default for the field 'Fiscal Position' (.property_account_position_id) in res.partner model based on the Country (country_id) selected for that contact. If Country is "United States (233)", Fiscal Position is "Fiscal Position for United States (3)"; else Fiscal Position is "International (5)"

Can someone tell me what I am doing wrong?

    _name = ‘res.partner’
    _inherit = ‘res.partner’ 

    country_id = fields.Many2one(‘res.country’, string=‘Country’,
                                help=“Apply only if delivery or invoicing country match.“)
    property_account_position_id = fields.Many2one(‘account.fiscal.position’, company_dependent=True,
                                                    string=“Fiscal Position”,help=“The fiscal position will determine taxes and accounts used for the partner.“,oldname=“property_account_position”,readonly=False) 
    @api.onchange(‘country_id’)
    def assign_fiscal_position(self):
        for record in self:if record.country_id == 233:
                record.property_account_position_id = 3
        else:
                record.property_account_position_id = 5
