Here's an example of a purely function-based implementation of an enemy generator: The enemyfunction creates an enemy with several attributes, such as ancestry, a weapon, health points, and a defense rating. Our first instance method is printInfo that lists all properties except isOnSale. Each of these initializations sets a property of the created object to the value of the corresponding parameter. Nowadays the students will search for the List of Object-Oriented Programming Projects on the internet but most of the time they need projects just for getting the idea. Actually, it's my college project and I've to make something by using OOP. Therefore, Python will use the newly defined printInfo method in Sandal over the inherited printInfo method from Shoe when the printInfo method is called. An object is simply a collection of data (variables) and methods (functions) that act on those data. Educative’s text-based courses are easily skimmed and give you the experience you need to land a job. Many beginners prefer to use OOP languages because they organize data much like how the human brain organizes information. You will also see the demonstration of source code implementation for each topic. In this case, self allows the method to access any parameter within the object this method is called on.
