How to Handle Multiple Web Elements with Selenium in Python: A Step-by-Step Guide

When working with Selenium to automate web tests in Python, you may encounter scenarios where two web elements have similar attributes but differ in ID. For instance, you might find two div elements, one with the ID phone_number_1-42 and the other contact_seller_1-42. This can make it challenging when you want to execute conditional actions based on their presence on the page.

In this guide, we will cover how to properly check for these elements and interact with them using Selenium in Python. Don't worry; by the end of this article, you'll have all the essential techniques down!

Understanding the Problem

Often, developers mistakenly use find_element to search for web elements. However, if the element does not exist, this method raises a NoSuchElementException error. This can cause issues in flow control, especially when multiple elements can be present at the same location.

For example, consider this initial approach that leads to problems:

In the code above, if phone_reveal_1 doesn't find an element, the script will break due to the raised exception.

Solution: Using find_elements()

To effectively handle such cases, the preferred way is to use find_elements(), which returns a list of matching elements and never raises an exception if no elements are found. Here's how you can implement this:

Method 1: Using Conditional Statements with find_elements()

Explanation:

find_elements_by_id returns a list; if no element is found, it results in an empty list.

You can check the length of the list to confirm the presence of an element. If it exists, you perform the click action; if not, you check the next condition.

Method 2: Using Try and Except Blocks

Another approach is to nest try-except blocks to handle the situation:

Explanation:

In this method, you attempt to click the first element. If it doesn't exist, the exception is caught, and the script attempts to click the second element. If that too fails, a message indicates the absence of both elements.

Conclusion

When working with Selenium and multiple web elements that may or may not be present, it's essential to choose the right method to check their existence. By employing find_elements() instead of find_element(), you can avoid unnecessary exceptions and make your automated tests more reliable.

Implement these techniques in your code to streamline your Selenium automation process and handle conditions with ease. Happy coding!
