Cocalc 01 Object Oriented Programming Ipynb

Object Oriented Programming (OOP) tends to be one of the major obstacles for beginners when they are first starting to learn Python. There are many, many tutorials and lessons covering OOP so feel free to Google search other lessons, and I have also put some links to other useful tutorials online at the bottom of this... For this lesson we will construct our knowledge of OOP in Python by building on the following topics: Learning about Special Methods for classes Lets start the lesson by remembering about the Basic Python Objects. For example:

Class and instance: Classes provide a means of bundling data and functionality together. Creating a new class creates a new type of object, allowing new instances of that type to be made. Each class instance can have attributes attached to it for maintaining its state. Class instances can also have methods (defined by its class) for modifying its state. (https://docs.python.org/3/tutorial/classes.html) Constructor: The constructor is called upon creating the new intance of a class.

Python first calls the new() method, which is the constructor, to create the object and then calls the init() method to initialize the object’s attributes. class keyword followed by the name of the class. The Naming convention is CamelCase for classes. Instance explicitly bound to the first parameter of each method. One can access the object's attributes using this parameter. Named self by convention, so attributes can be accessed like self.attribute and methods like self.method(params)
