How to Resolve Selenium's DeprecationWarning: executable_path has been deprecated?

DeprecationWarning: executable_path has been Deprecated - Exploring a Solution

Selenium WebDriver v4 has introduced changes that deprecate the use of the executable_path option. This article aims to address this issue and provide a solution using the latest version of Selenium and Webdriver Manager for Python.

The error message "DeprecationWarning: executable_path has been deprecated, please pass in a Service object" indicates that the executable_path argument, which was previously used to specify the path to the browser driver, is no longer supported.

Solution

To resolve this issue, you can utilize the Service class provided by Selenium WebDriver v4 along with the ChromeDriverManager() from the Webdriver Manager for Python. The following code block demonstrates the updated approach:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))

This code installs the appropriate browser driver using ChromeDriverManager().install() and then creates a Service object, which is passed to the WebDriver constructor.

Prerequisites

Before implementing this solution, ensure you have:

• Upgraded Selenium to version 4.0.0: pip3 install -U selenium
• Installed Webdriver Manager for Python: pip3 install webdriver-manager

Additional Considerations

If you wish to configure additional options, such as maximizing the browser window, you can use the Options() class as follows:

from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("start-maximized")
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)
