How to handle Angularjs / Javascript dropdown using Python / Selenium webdriver?

i want to automate some browser tasks using Python and Selenium webdriver on Chromium browser. My python script is already able to login, navigate to a subpage / do some clicks, and insert something into a form.

My problem is a mandatory dropdown list where i have to choose something before i can go on. I think the webpage contains angularjs / javascript at that point (third line in the code below) to create the dropdown, and i don't know how to handle that.

Problem seem to be 1) to locate the element (xpath seems to change sometimes), and 2) i'm unable to click or send keys to what i've found. Also i've tried some kinds of "WebDriverWait" and sleep commands and "wait.until(expected_conditions.visibility_of_element_located((By.XPATH, ...))"... no luck so far.

Is it at all possible to solve that problem with just Python and Selenium? Or do i need something like Protractor (and does Protractor just works with Javascript commands)? Also i've seen Pytractor...

I'm quite a Newbie concerning that stuff, could someone please explain what could be a good way to solve this problem? Thanks in advance... :)

Webpage code looks like this (grabbed using Firebug/Firepath):

<div class="ng-scope ng-isolate-scope" model-contains-key="true" ref="salutations" cat-input-select="editDetail.salutation">
    <div id="s2id_autogen1" class="select2-container form-control ng-untouched ng-valid ng-dirty ng-valid-parse">
        <a class="select2-choice select2-default" tabindex="-1" href="javascript:void(0)">
            <span id="select2-chosen-2" class="select2-chosen"/>
            <abbr class="select2-search-choice-close"/>
            <span class="select2-arrow" role="presentation">
                <b role="presentation"/>
            </span>
        </a>
