The first step is to confirm that Selenium has be instal in the right Python environment.

Open your pole or bidding prompt.

Run the next command:

pip display selenium

If Selenium is install correctly, you should see details like the version number and installation path. If nothing shows up, Selenium is not installed, and you & # 8217; ll need to establish it again usingpip install selenium.

Step 2. Test a Simple Selenium Script

After verifying that Selenium is installed, running a simple Selenium script is the better way to test the fix. This will confirm that the module can be spell and functions right.

Create a new Python hand (for instance,test_selenium.py).
Add the following code to launch a browser (ensure you have a compatible WebDriver establish, such as ChromeDriver or GeckoDriver for Firefox):

from selenium import webdriver # Start a new Chrome browser session driver = webdriver.Chrome () # or webdriver.Firefox () if expend Firefox # Open a website driver.get (`` https: //www.example.com '') # Verify the page title print (`` Page rubric is: '', driver.title) # Close the browser driver.quit ()
