I am using Python selenium to automate my attendance entry. It was working fine, now I wanted to try by modifying the source code. I have seen few posts stating that it can be modified using driver.execute_script() and it works for JavaScript, but in my case I need to modify a source code under the select tag. I was able to modify the source code using the inspect element. The following is select tags source code:
<select name="date1">
<option value="2016-09-17">2016-09-17</option>
<option value="2016-09-16">2016-09-16</option>
<option value="2016-09-14">2016-09-14</option>
</select>
I tried to do it with driver.execute_script(). The following was my code:
sel = driver.find_element_by_xpath('/html/body/div[3]/div/div[2]/form/table/tbody/tr[2]/td[3]/select')
input_list = sel.find_element_by_tag_name('option')
cmd = "input_list.value = '2016-09-07'"
driver.execute_script(cmd)
But the above code is giving me the following error:
selenium.common.exceptions.WebDriverException: Message: input_list is not defined
I am able to modify the source code using the inspect element window. Is there any way to modify the source code using selenium?

Try following solution and let me know if any issues occurs:
driver.execute_script("""document.querySelector("select[name='date1'] option").value="2016-09-07";""")
P.S. I advise you not to use absolute XPath in your selectors, but relative instead

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';<html>
<body>
<div></div>
<div></div>
<div>

<div>

<select name="date1">
<option value="2016-09-17">2016-09-17</option>
<option value="2016-09-16">2016-09-16</option>
<option value="2016-09-14">2016-09-14</option>
