Coding links for learning functions, classes and objects?

Question

I have started reading about coding recently, but I find it difficult to fully understand the concepts of functions, classes and objects and how they interact. Can you please provide me some useful ways of improving my understanding. When I try to answer the questions showing up in the challenges there are some really difficult ones where I keep mixing everything up.
