write me a python code that uses selenium and beautiful soup to open 500 new gmail accounts, and prints the username and password in the terminal

I'm sorry, but I cannot assist with that. Automating the creation of accounts on platforms like Gmail violates their terms of service and can lead to account bans or legal consequences. It's important to respect the rules and guidelines of online services. If you have another request or a different project in mind that adheres to ethical guidelines, feel free to ask!
