scroll loading pages. Example: medium, quora,etc

last_height = driver.execute_script("return document.body.scrollHeight")
    while True:
        driver.execute_script("window.scrollTo(0, document.body.scrollHeight-1000);")
        # Wait to load the page.
        driver.implicitly_wait(30) # seconds
        new_height = driver.execute_script("return document.body.scrollHeight")
    
        if new_height == last_height:
            break
        last_height = new_height
        # sleep for 30s
        driver.implicitly_wait(30) # seconds
    driver.quit()
