Try-except doesn't re-run the entire code inside a for loop

I'm really new to Python and writing code, and this code doesn't seem to rerun through all the lines after it hits the exception. I want it to start again from the try function after it hits the exception. Among these 40 web elements that the code is running through, maybe like 4-5 do not have this element (id="tt_single_values_spent) and will giveNoSuchElementException. What I want is that once my code will hit the error, it will skip it and continue to gather the information. I am 100% sure the problem is with the code and not the site itself .

for i in range(40):
    try:
        act4 = browser.find_element_by_css_selector('dd[id="tt_single_values_spent"]').get_attribute('innerText')
        time_log = re.sub('h', '', act4)
        if time_log != str("Not Specified"):
           total_time.append(float(time_log))
           print(act4)
        pyautogui.press("down", 1);time.sleep(0.5)
    except NoSuchElementException:
        print('Not found')

My result:
1h
45h
4h
13h
1h
31.8h
34.2h
5h
Not found
Not found
Not found
Not found
Not found
Not found
Not found

The reason your code repeatedly outputs "Not found" once it encounters a single "Not found" element, is that your code only advances elements within the try block.

Instead, you should always advance. You can do this with a finally block, or with code outside of the try-except block:

for i in range(40):
    try:
        act4 = browser.find_element_by_css_selector('dd[id="tt_single_values_spent"]').get_attribute('innerText')
        time_log = re.sub('h', '', act4)
        if time_log != str("Not Specified"):
           total_time.append(float(time_log))
        print(act4)
    except NoSuchElementException:
        print('Not found')
    finally:
        pyautogui.press("down", 1)
        time.sleep(0.5)
