#set geckodriver.exe path
driver = webdriver.Firefox(executable_path="C:\geckodriver.exe")
driver.maximize_window()
#launch URL
driver.get("https://www.tutorialspoint.com/index.htm")
#add cookie
c = {'name' : "Automation", 'value' : 'QA'}
driver.add_cookie(c);
#count total cookies
print(len(driver.get_cookies()))
#obtain cookie with name
print(driver.get_cookie("Automation"))
#delete cookies
driver.delete_all_cookies();
#check cookies after delete
d = driver.get_cookies()
print("Cookie count after all deletion")
print(len(d))
#close browser
