Selenium radio buttons trouble clicking

Selenium radio buttons trouble clicking

I am having MUCH trouble with selenium, as I don't even understand how the
xpath works. I'm trying to make a script which selects a random radio
button out of the available buttons. Heres the source code for the part of
the page i'm interested in:
<input class="answerListOption hideOther answerCommentRequired
answerCommentRequired190620_0" type="radio" name="survey_answer[190620][]"
value="686346" data-mustcomment="answerCommentRequired190620" />
<span class="answerText">xBox</span>
</label>
</li>
<li class="answerRowBox_4">
<label>
<input class="answerListOptions answerlistradio" type="radio"
name="survey_answer[190620][]" value="-3117" tabindex="-1"/>
<span class="answerText">n/a</span>
</label>
</li>
<li class="e848aca52a896563b17cd1484b2e3805">
<label>
<input class="answerListOption hideOther answerCommentRequired
answerCommentRequired190620_0" type="radio"
name="survey_answer[190620][]" value="686347"
data-mustcomment="answerCommentRequired190620" />
<span class="answerText">PS4</span>
</label>
</li>
<li class="bae58c269d9264734bf527ceb86bcb86">
<label>
<input class="answerListOption hideOther answerCommentRequired
answerCommentRequired190620_0" type="radio"
name="survey_answer[190620][]" value="686348"
data-mustcomment="answerCommentRequired190620" />
<span class="answerText">N/A</span>
</label>
</li>
<li class="answerRowBox_4">
<input type="text" name="survey_answer[190620][-5630]"
class="inputText charCounter" maxlength="150" data-maxlength="150"
name="Input3" value="" tabindex="-1" />
</li>
</ul>
Its a few different radio buttons, with different awnsers. One is for
xbox, other is for ps3. How would I select one of these radio buttons?
I'm trying to select one of them by the name "survey_awnser" as its the
only thing that doesn't change.
