Instantiation is the act of creating an object from a specific set of instructions, which is called an instance. If classes are blueprints, instances are the houses built from their instructions; every new instance of Character is its object, just like two houses built from the same instructions are still two different physical structures. What happens to one doesn't have any repercussions on the other.
In the previous chapter, Control Flow and Collection Types, we created lists and dictionaries, which are classes, using their types and the new keyword. We can do the same thing for custom classes such as Character, which you'll do next.
