How to Wait for Multiple Elements to Load in Python Selenium?

Python Selenium: Await Loading of Multiple Elements

Your task involves ensuring that a dynamic list, loaded via AJAX, has multiple li elements before proceeding. The list initially displays a loading message before the actual content becomes available.

Solution Using WebDriverWait with Custom Conditions

The recommended approach is to employ WebDriverWait with a lambda function to define a custom condition. This function allows you to verify that the number of located elements exceeds a specified minimum:

<code class="python">from selenium.webdriver.support import expected_conditions as EC

num_elements = 1
WebDriverWait(driver, timeout).until(
    lambda d: len(d.find_elements_by_css_selector('ul.ltr li[id^="t_b_"] a[id^="t_a_"]')) > num_elements
)</code>

Alternative Approaches

• Using ExpectedConditions.presence_of_element_located(): This condition verifies the presence of a specified element, but it doesn't guarantee its visibility or state.
• Using ExpectedConditions.visibility_of_all_elements_located(): This condition ensures that all elements within a locator are visible. This can be used to wait for a specific number of visible elements, but it requires the elements to be present in the DOM from the beginning.

Note

The CSS_SELECTOR and XPATH locators used in the code example can be modified to match your specific element identifiers.
