Unable to find elements after switching to iframe in Selenium python

Question

I'm running a test case and part of it is to check if an element in an iframe is visible I have done the below but it's not working and always goes to the except block. Thank you

try:
    time.sleep(2)
    driver.switch_to.frame("iframe-xxxxxxxxxxxxxxxxxx")
    time.sleep(2)
    if driver.find_element_by_xpath("//div[@class='col-11 answer-feedback-label']//div[contains(text(),'Hello World!')]"):
        logging.info("Success")
except:
     logging.error("Failure")

To check if an element in an <iframe> is visible or not, as the the desired element is with in an <iframe> so you have to:

• Induce WebDriverWait for the desired frame_to_be_available_and_switch_to_it().
• Induce WebDriverWait for the visibility_of_element_located().

• You can use the following solution:

  • Code Block:

    from selenium import webdriver
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.support import expected_conditions as EC
    from selenium.webdriver.common.by import By
    import org.openqa.selenium.TimeoutException;
    .
    .
    .
    try:
    
        WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"iframe_XPATH")))
        WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//div[@class='col-11 answer-feedback-label']//div[contains(text(),'Hello World!')]")))
        logging.info("Success")
    except TimeoutEception:
         logging.error("Failure")
