The problem is that execute_script executes JavaScript inside the browser [1], which knows nothing about python variables in python script. In particuar input_list is not defined for JavaScript, since it's a python variable.

To fix this, you can select the element inside the JavaScript file. To do this, you can set your cmd to something like this [2]:

    function getElementByXpath(path) {
      return document.evaluate(path, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
    }

    getElementByXpath("/html/body/div[3]/div/div[2]/form/table/tbody/tr[2]/td[3]/select/option[1]").value = '2016-09-07';

                      2016-09-14
