I am using Python and Selenium to add certain information to a form.
In this case, I need to insert the city of residence, selecting it from an auto-complete drop-down menu.
Altough the list is dynamic and may change depending on other values, to illustrate, I would like to select "Roma".
How can I effectively find and select a value from a list that is dynamically changing, using Selenium?
I tried with the methodology explained 
Snippets of the html code from the page are the following:
<input autocomplete="off" placeholder=" " id="dx_dx-e8acb639-2bdd-7dda-710a-2d81f408dc73_ComuneNascitaPk" aria-haspopup="listbox" aria-autocomplete="list" type="text" spellcheck="false" tabindex="0" role="combobox" aria-expanded="false" aria-required="true">
From the expanded list:
<div style="transform: translate(0px, 0px);"><div role="option" aria-selected="false"><div >Affile</div></div><div role="option" aria-selected="false"><div >Agosta</div></div><div role="option"

You really can't use Select class since you're trying to handle div node not select node...
You can use this approach to select reqired value
