Python Selenium - Try/Except does not work

Question

I have a Selenium script, where I enter a series of websites, and get some data. Sometimes the data does not exist, and I simply want to write something like "Cant find x data" onto my string. The current script does this:

#Getting "Status"
try:
    strValue = strValue + ',' + browser.find_element_by_css_selector('#visKTTabset > div.h-tab-content > div.h-tab-content-inner > div:nth-child(12) > table > tbody > tr.stripes-even > td:nth-child(3) > span').text
except webdriver.NoSuchElementException:
    StrValue = strValue + ',' + "Status not found"

The script works when the "Status" actually exists, but id does not get into the "except" part. The top of my script has this:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import NoSuchElementException

browser = webdriver.Chrome(executable_path=r'C:\Selenium\chromedriver.exe')
browser.get('https://motorregister.skat.dk/dmr-front/dmr.portal?_nfpb=true&_nfpb=true&_pageLabel=vis_koeretoej_side&_nfls=false')
browser.implicitly_wait(10)  # Will set the global wait to 10 seconds.gnash

I tried the solution here: Try except in python/selenium still throwing NoSuchElementException error but it didnt work.

It returns an exit code so it doesn’t qualify for the exception — x3l51, Apr 23 '19 at 08:14
@anonjnr I get this error: selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"#visKTTabset > div.h-tab-content > div.h-tab-content-inner > div:nth-child(12) > table > tbody > tr.stripes-even > td:nth-child(4) > span"} — Ercan Ciftci, Apr 23 '19 at 08:20
See answer below. Also you could do something like strValue = 0 and use an if Statement instead of the try block? — x3l51, Apr 23 '19 at 08:26

Python names are case sensitive, so perhaps you need:

strValue = strValue + ',' + "Status not found"

Good point! That fixed some other issues that I had! Thank you – Ercan Ciftci Apr 23 '19 at 08:27
Just one other note: the Pythonic way of naming variables is dash_case not camelCase. So str_value is more appropriate. :) – mighty_mike Apr 23 '19 at 08:33

NoSuchElementException is not part of webdriver, it's part of selenium.common.exceptions

try:
    strValue = strValue + ',' + browser.find_element_by_css_selector('#visKTTabset > div.h-tab-content > div.h-tab-content-inner > div:nth-child(12) > table > tbody > tr.stripes-even > td:nth-child(3) > span').text
except NoSuchElementException:  # without webdriver.
    StrValue = strValue + ',' + "Status not found"

And make sure strValue is declared before the try except block.

As a side note, in Python strValue should be str_value

Thank you so much. I've been stuck with this, for far too long, your solution - along with Brunns answer helped out — Ercan Ciftci, Apr 23 '19 at 08:29
