How do I get a Different Random Choice When People Decided to Play Again? Python

I'm basically trying to get a different enemy every single time that people play/runs the code. For now, If I decided to play again the code keeps using the same values as before and I really want them to be different. Please help me. I'm New to using Python!

I left you the whole code of the program in case It helps you to help me. Thanks! I hope I will help others soon.
