input: Write a function to automate the login process in a given website using Selenium in Python. The function should initialize the web driver, navigate to the target website, locate the username and password fields, input the credentials, and submit the form. The function should also print "Login successful!" if the login is successful. If the website is empty, the function should print "No website provided."
