Hi i newbie in python and odoo.

Can i return value from python code to action domain in xml or not ?

because i need to use domain like [('create_uid','=',...)] <--- number in array

<record id="purchase_rfq_sale" model="ir.actions.act_window">            
<field name="name">Requests for Quotation(Sale)</field>            
<field name="type">ir.actions.act_window</field>
