Find Elements in Selenium with Python: A Complete Guide

Written by Vincent N. | Sep 11, 2025 12:45:00 PM

When you write a Selenium test, every interaction depends on one crucial step: identifying the right element. Whether it's a button, input field, dropdown, or link, Selenium must find it before it can click, type, or select.

This is where element locators come in. These strategies help your Python scripts pinpoint specific pieces of the page, just like a user would. In this guide, you'll learn exactly how to find element in Selenium with Python confidently and consistently.

Here’s what we’ll cover:

  • What are elements in Selenium?
  • How element locators help Python tests interact with the page
  • Setting up Selenium with Python
  • Hands-on examples using every locator strategy
  • Best practices for reliable element targeting
  • Running your Python Selenium tests across real devices and browsers

Let’s get started!

What are Elements in Selenium?

Web elements are the pieces that make up a webpage. Each button, image, link, input field, or dropdown is an element. Selenium works by finding these elements and interacting with them in the same way a user would.

To find element in Selenium with Python, your script needs to know exactly which part of the page it should touch. That could mean clicking a link, filling a form, or verifying a label. Every action begins with the right element.

Think of a webpage like a LEGO model. Each block has a shape and position, and every Selenium test script needs to know which block to work with. This understanding allows your Python code to act with precision and purpose.

Once you know how to target an element, the rest of the automation becomes much easier to manage.

What are Element Locators in Selenium?

To find element in Selenium with Python, your script needs a clear strategy. That strategy is called a locator. A locator helps Selenium identify the exact element it should interact with, even when there are hundreds of similar elements on the page.

Accurate locators lead to stable tests. They reduce flakiness and improve reliability. That’s why choosing the right locator from the beginning makes a big difference in test performance.

Here are the most common locator strategies used in Selenium:

  • By ID: Best when the element has a unique identifier.
  • By Name: Works well for form elements with name attributes.
  • By Class Name: Useful when class names are unique or specific.
  • By Tag Name: Great for selecting groups like all input or button elements.
  • By Link Text / Partial Link Text: Ideal for links when you know the displayed text.
  • By CSS Selector: Very flexible for targeting complex or nested elements.
  • By XPath: Helps locate elements based on structure, especially when attributes are dynamic.

Each locator gives you a different angle to approach the page structure. Before jumping into code, it helps to know which method fits your test case best.

Setting Up Selenium with Python

Before you can find element in Selenium with Python, you need to prepare your environment. The setup is simple and ensures your tests run smoothly.

Follow these steps to get started:

  1. Install Python and pip on your machine. Make sure the version matches your project requirements.
  2. Use pip to install Selenium: pip install selenium. This adds the WebDriver interface to your Python environment.
  3. Download and configure the WebDriver for your chosen browser. For Chrome, get ChromeDriver; for Firefox, get GeckoDriver. Ensure the driver version matches your browser.
  4. Write a simple script to launch a browser and open a webpage. For example, open katalon.com and verify the page loads.

After completing these steps, run a basic “Hello World” test to confirm everything works. You can now start locating elements and interacting with them in your Python Selenium scripts.

How to find Elements in Selenium with Python?

Once your environment is ready, you can start locating elements in Selenium with Python. Each locator strategy has its own use case, and combining them correctly ensures stable and efficient tests.

Find element by ID: Use when the element has a unique identifier.

Python
element = driver.find_element(By.ID, "submit_button")

Find element by Name: Targets elements with a name attribute.

Python
element = driver.find_element(By.NAME, "username")

Find element by Class Name: Use when a class is unique for the element.

Python
element = driver.find_element(By.CLASS_NAME, "login-field")

Find element by Tag Name: Useful for groups like all input or button elements.

Python
element = driver.find_element(By.TAG_NAME, "button")

Find element by Link Text / Partial Link Text: Targets links by exact or partial text.

Python
element = driver.find_element(By.LINK_TEXT, "Contact Us")
partial_element = driver.find_element(By.PARTIAL_LINK_TEXT, "Contact")

Find element by CSS Selector: Flexible and precise targeting.

Python
element = driver.find_element(By.CSS_SELECTOR, "div.login input#username")

Find element by XPath: Useful when other attributes are not reliable.

Python
element = driver.find_element(By.XPATH, "//input[@id='username']")

You can also use find_elements() to locate multiple elements at once. For example:

Python
buttons = driver.find_elements(By.TAG_NAME, "button")

Choosing the right locator ensures your Selenium Python tests remain stable, fast, and maintainable. Using unique identifiers and robust strategies reduces flakiness and increases test reliability.

Best Practices for Locating Elements in Selenium with Python

Finding elements effectively is more than writing code. Following best practices ensures your Selenium Python tests remain stable, fast, and maintainable over time.

  • Prefer unique IDs: When available, IDs provide the fastest and most reliable way to locate elements.
  • Use CSS selectors strategically: CSS selectors offer flexibility for nested or styled elements. Keep XPath as a fallback for complex paths.
  • Avoid brittle locators: Dynamic attributes can change often. Target attributes that are stable and unlikely to break with UI updates.
  • Centralize locator definitions: Store all element locators in one place. This makes updates easy and keeps your scripts consistent.
  • Combine with explicit waits: Use waits for elements that load dynamically. This ensures your scripts interact with elements only when ready.
  • Regularly review and update locators: UI changes over time. Periodic checks keep your Selenium Python tests reliable and effective.

By applying these practices, you make your tests more readable, maintainable, and resilient to UI changes, improving long-term test quality.
