Conditional if element is on website refresh and if not move on with the code

Question

I'm trying to get this conditional working but I'm getting traceback. I want to look if the element is present on the website and if it is refresh and execute redeem_func() and if the element is not present at all I want to not execute err_reddem_func() and move on to this By the way, I don't know if it's relevant but if there was no error on the webpage it redirects to the last step website and saves URL to txt.

Exception in thread Thread-6:
Traceback (most recent call last):

My Code

def redeem_func():
        capHome = cap_home()
        print("redeem_func")
        driver.execute_script("redemptionValidation(\"" + capHome + "\")")
        time.sleep(10)


    redeem_func()
    time.sleep(1)
    print(driver.current_url)

    def err_redeem_func():
        err_redeem = driver.find_element_by_class_name('error')
        try:
            if err_redeem.is_displayed() and err_redeem.is_enabled():
                driver.refresh()
                redeem_func()
        except NoSuchElementException:
            pass


    err_redeem_func()

    print(driver.current_url)
    print("SAVING TO TXT")
    finalCode = driver.current_url
    f = open('t.txt','a')
    f.write('\n' + finalCode)
    f.close()

Replace the below line

if err_redeem.is_displayed() and err_redeem.is_enabled():

with

if (len(driver.find_elements_by_class_name('error'))>0):

You are getting NoSuchElement exception because the script is trying to check if the element is enabled when the element is not there on the page.

But the new code doesn't check if the element is visible. You can add that after the len() check and it won't throw if the element isn't there.
