Certainly! Below is a Python script using Selenium to perform the specified tasks: displaying cookies before and after login on https://www.saucedemo.com/, logging in, and then logging out.

from selenium import webdriver

Function to display cookies

def display_cookies(driver):
cookies = driver.get_cookies()
print("Cookies:")
for cookie in cookies:
print(f"{cookie['name']}: {cookie['value']}")
print()

Initialize the Chrome WebDriver

driver = webdriver.Chrome()

try:
# Open the Saucedemo website
driver.get("https://www.saucedemo.com/")

# Display cookies before login
print("Before Login:")
display_cookies(driver)

# Login
username = "standard_user"
password = "secret_sauce"

driver.find_element_by_id("user-name").send_keys(username)
driver.find_element_by_id("password").send_keys(password)
driver.find_element_by_id("login-button").click()

# Display cookies after login
print("After Login:")
display_cookies(driver)

# Logout
driver.find_element_by_id("react-burger-menu-btn").click()
driver.find_element_by_id("logout_sidebar_link").click()

# Display cookies after logout
print("After Logout:")
display_cookies(driver)

finally:
# Close the browser window
driver.quit()
This script uses the Chrome WebDriver, so make sure you have the ChromeDriver executable in your system's PATH or specify its location. You can download ChromeDriver from https://sites.google.com/chromium.org/driver/.
