Hello Mame Penda Bathily,
Try below code:
class SaleOrderLine(models.Model):
_inherit = 'sale.order.line'
with_cloth = fields.Boolean('With Cloth')     *#Add this field in view.*
*@api.onchange('with_cloth')
def onchange_with_cloth(self):
if self.with_cloth:
self.price_unit = self.product_id.lst_price - 2000
else:
self.price_unit = self.product_id.lst_price*
Hope this will helps you.
Thanks,
