I'm trying to locate element by 

element=driver.find_element_by_partial_link_text("text")

in Python selenium and the element does not always exist. Is there a quick line to check if it exists and get NULL or FALSE in place of the error message when it doesn't exist?

Sometimes the element does not appear at once, for this case we need to use explicit wait:

browser = webdriver.Chrome()
wait = WebDriverWait(browser, 5)

def is_element_exist(text):
    try:
        wait.until(EC.presence_of_element_located((By.PARTIAL_LINK_TEXT, text)))
    except TimeoutException:
        return False

Solution without try/ except:

def is_element_exist(text):
    elements = wait.until(EC.presence_of_all_elements_located((By.PARTIAL_LINK_TEXT, text)))
    return None if elements else False

How explicit wait works you can read here.
