Object-oriented programming, or OOP for short, is a way of writing computer programs that helps us to think about problems differently. It makes it easier for us to solve problems because objects (like people, animals, robots, etc.) can interact with each other in a program. For example, if you wanted to write a program about a school where students have classes with teachers, OOP would help you break down the problem into smaller pieces. You could have a student object and a teacher object, and each object could have different properties and methods that could interact with each other. So, when you program with OOP, you are thinking about problems in terms of objects and how they interact with each other to solve your problem.
