catching error in python using try except

I have the following code:

from selenium.webdriver import Firefox
from selenium.webdriver.common.keys import Keys
from selenium.webdriver import ActionChains
from selenium.common.exceptions import NoSuchElementException
import time

while True:
    try:
        
        url = 'https://finance.yahoo.com/'
        driver_path = 'C:\\Users\\inder\\geckodriver.exe'
        
        browser = Firefox(executable_path = driver_path)
        browser.get(url)
        
        search_field_id = 'yfin-usr-qry'
        
        element_search_field = browser.find_element_by_id(search_field_id)
        element_search_field.clear()
        element_search_field.send_keys('TSLA')
        element_search_field.send_keys(Keys.ENTER)
        time.sleep(5)
        xpath_string = '/html/body/div[1]/div/div/div[1]/div/div[2]/div/div/div[6]/div/div/section/div/ul/li[2]/a/span'
        element = browser.find_element_by_xpath(xpath_string)
        action_chains = ActionChains(browser)
        action_chains.move_to_element(element).click().perform()
        break
    except NoSuchElementException as e:
        print(e)
        pass

This code works fine what i am trying to do is if for some reason if the page has not loaded correctly, i would like the entire code block to run again. To do this i have identified the search field element_search_field. If the element is not found ordinarily i would get an error:

NoSuchElementException: Unable to locate element: /html/body/div[1]/div/div/div[1]/div/div[2]/div/div/div[6]/div/div/section/div/ul/li[2]/a/span

However when i try to catch this exception with my above code i am getting an error:

NameError: name 'NoSuchElementException' is not defined

Please advise what can I do to resolve this issue.

I haven't had this problem myself but the Selenium documentation lists the common exceptions. So maybe you can try:

from selenium.common.exceptions import NoSuchElementException

Do you use pycharm? If you use pycharm,It will remind you that the code is wrong You should do this.

from selenium.common.exceptions import NoSuchElementException

And i can't find the declare variable action_chains in your code.It's like a mistake
