Wait for page redirect Selenium WebDriver (Python)

Question

I have a page which loads dynamic content with ajax and then redirects after a certain amount of time (not fixed). How can I force Selenium Webdriver to wait for the page to redirect then go to a different link immediately after?

import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait

driver = webdriver.Chrome();
driver.get("http://www.website.com/wait.php") 

Answer 1

You can create a custom Expected Condition to wait for the URL to change:

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait

wait = WebDriverWait(driver, 10)
wait.until(lambda driver: driver.current_url != "http://www.website.com/wait.php")

The Expected Condition is basically a callable - you can wrap it into a class overwriting the __call__() magic method as the built-in conditions are implemented.
