from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
import time

# Specify the path to your ChromeDriver executable
# service = Service('/path/to/your/chromedriver') # Update this path
# driver = webdriver.Chrome(service=service)

# For simpler setups, you might use:
driver = webdriver.Chrome() # Ensure chromedriver is in your PATH or installed via webdriver_manager

driver.get("https://www.example.com")
time.sleep(5) # Wait for the page to load

# Example: Find an element by its ID and print its text
# element = driver.find_element(By.ID, "some_element_id")
# print(element.text)

driver.quit()

This simple example demonstrates opening a website, waiting, and then closing the browser. The real power comes from combining find_element with various locators and performing actions on those elements.
