Using if/else under a try method to login, however a successful login throws exception

Here is the snippet of the code I think is having a loop bug. I have been successful in having it retry upon failure or blank entry.
But once it logs in, it still keeps trying to login. Could someone take a look?

print(f"The stripped captcha text is: {result}")
time.sleep(1)
if result:
    try:
        driver.find_element(By.XPATH,"//div[@id='app']//div[contains(@class, 'el-input')]//input[@name='captcha']").send_keys(result)
        driver.find_element(By.XPATH,"//div[@id='app']//button[contains(@type,'button')]").click()
        print("Captcha has been entered")
        time.sleep(2)
        login_button = driver.find_element(By.XPATH,"//div[@id='app']//form[@class= 'el-form login-form el-form--label-left']//button[contains(@type,'button')]")
        if login_button:
            #try again by page refresh
            print("Captcha was entered but was wrong, trying again...")
            driver.refresh()
            login_attempt()
        else:
            print("The login attempt worked!")
    except:
        print("Seems to me that you are already logged in, but I will keep repeating this until you solve this loop")
        time.sleep(2)
        login_button = driver.find_element(By.XPATH,"//div[@id='app']//form[@class= 'el-form login-form el-form--label-left']//button[contains(@type,'button')]")
        if login_button:
            #try again by page refresh
            print("Even after being logged in, trying again...this is not right.")
            driver.refresh()
            login_attempt()
        else:
            print("The login attempt may have worked!")
else:
    print("The captcha result was maybe blank.")
    time.sleep(2)
    if login_button:
        #try again by page refresh
        driver.refresh()
        time.sleep(2)
        login_attempt()
    else:
        print("The login attempt worked!")

Sample Output:

Login button was found and variable has been recorded
Login attempt was called by your code
Username and Password were entered
The stripped captcha text is: vyiw4
Captcha has been entered
Captcha was entered but was wrong, trying again...
Login attempt was called by your code
Username and Password were entered
The stripped captcha text is: fhxax
Captcha has been entered
Seems to me that you are already logged in, but I will keep repeating this until you solve this loop
Seems to me that you are already logged in, but I will keep repeating this until you solve this loop

I tried to implement a re-attempt at failure logic, but failed to implement a successful scenario logic. I have no clue how to avoid the code to keep retrying, it is almost as if it skips the below else condition:

else:
    print("The login attempt worked!")

I added a comment but figured I'd add a response to be more clear. I'm assuming this is selenium- if so you should tag it as such. The other assumption I am making is that the login button is not present after a successful login.

The main issue I see is that you are not handling the element not being present and assuming login_button will always be True/False, but in reality it will throw a NoSuchElementException. Also, it appears that your retry logic is too circular.

In your example:

• If captcha is found: try logging in
• If captcha is not found: try logging in
• If login appears to be successful: try logging in

In what scenario would it stop attempting to login?

Try something like this:

from selenium.common.exceptions import NoSuchElementException

print(f"The stripped captcha text is: {result}")
time.sleep(1)
if result:
    driver.find_element(By.XPATH,"//div[@id='app']//div[contains(@class, 'el-input')]//input[@name='captcha']").send_keys(result)
    driver.find_element(By.XPATH,"//div[@id='app']//button[contains(@type,'button')]").click()
    print("Captcha has been entered")
    time.sleep(2)
    try:
        login_button = driver.find_element(By.XPATH,"//div[@id='app']//form[@class= 'el-form login-form el-form--label-left']//button[contains(@type,'button')]")
        if login_button:
            #try again by page refresh
            print("Captcha was entered but was wrong, trying again...")
            driver.refresh()
            login_attempt()
    except NoSuchElementException:
        print("The login attempt worked!")
else:
    #further check login status or assume user is already logged in

Also, instead of waiting a fixed 2s you could also utilize selenium's WebDriverWait:

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

wait = WebDriverWait(driver, 10)  #10s timeout
wait.until(EC.visibility_of_element_located((By.XPATH, "XPATH STRING")))
#continue code
