How to Resolve the 'to_capabilities()' Missing Argument Error When Opening a Chrome Profile with Python?

Opening a Chrome Profile using Python

Problem Statement

While attempting to open a Chrome profile using Python, an error is encountered stating that 'to_capabilities()' is missing a positional argument.

Solution

To successfully open a Chrome profile using Python, you need to:

1. Create a New Profile:

   • Open Chrome and navigate to chrome://settings/.
   • Click on "Manage other people" and add a new person with a unique name, icon, and create a desktop shortcut.

2. Get the Profile Directory:

   • Right-click on the desktop shortcut of the newly created profile and select "Properties."
   • Copy the value of the "--profile-directory" argument.

3. Set Chrome Options:

   • Create an instance of webdriver.ChromeOptions and add the "user-data-dir" argument with the profile directory path.

Here's the updated Python code:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

# Create Chrome options
options = Options()
options.add_argument("--user-data-dir=C:\Users\princess\AppData\Local\Google\Chrome\User Data\Profile 1")

# Open Chrome with the specified profile
browser = webdriver.Chrome(executable_path=r"C:\Users\princess\AppData\Local\Programs\Python\Python36-32\chromedriver.exe", chrome_options=options)

# Navigate to a website (for testing purposes)
browser.get("https://www.google.com")

By following these steps, you can open a specific Chrome profile using webdriver.Chrome and interact with web applications using that profile.
