How to Use Selenium with Python: Simple Guide and Example

To use selenium with Python, first install the selenium package and a browser driver like ChromeDriver. Then, import webdriver from selenium, create a browser instance, and use it to open web pages and interact with elements.

Syntax

Here is the basic syntax to start using Selenium with Python:

• from selenium import webdriver: Import the webdriver module.
• driver = webdriver.Chrome(): Create a new Chrome browser instance.
• driver.get('URL'): Open a web page by URL.
• driver.quit(): Close the browser when done.

python

from selenium import webdriver

driver = webdriver.Chrome()
driver.get('https://www.example.com')
driver.quit()

Example

This example opens the Python official website, prints the page title, and then closes the browser.

python

from selenium import webdriver

# Create a new Chrome browser instance
driver = webdriver.Chrome()

# Open the Python official website
driver.get('https://www.python.org')

# Print the page title
print(driver.title)

# Close the browser
driver.quit()

Common Pitfalls

Common mistakes when using Selenium with Python include:

• Not installing the correct browser driver or not adding it to your system PATH.
• Forgetting to call driver.quit(), which leaves the browser open.
• Trying to interact with elements before the page fully loads.
• Using outdated Selenium or driver versions causing compatibility issues.

Always ensure your Selenium package and browser driver versions match your browser version.

python

from selenium import webdriver

# Wrong: Not quitting the browser
# driver = webdriver.Chrome()
# driver.get('https://www.python.org')
# print(driver.title)

# Right: Always quit the browser

driver = webdriver.Chrome()
driver.get('https://www.python.org')
print(driver.title)
driver.quit()

Output

Quick Reference

Here is a quick reference for common Selenium with Python commands:

Command	Description
webdriver.Chrome()	Starts a new Chrome browser session
driver.get(URL)	Navigates to the specified URL
driver.find_element(By.ID, 'id')	Finds an element by its ID
driver.find_element(By.NAME, 'name')	Finds an element by its name attribute
driver.quit()	Closes the browser and ends the session

Key Takeaways

Install Selenium and the correct browser driver before starting.

Use webdriver to open browsers and interact with web pages.

Always close the browser with driver.quit() to free resources.

Wait for pages to load before interacting with elements.

Keep Selenium and drivers updated to avoid compatibility issues.
