Description:
Examine the advanced features that you can implement by using classes in Python, such as special methods, iterators, class properties, and abstract base classes. Key concepts covered in this 14-video course include how to represent objects by using customized strings; performing addition operations on custom objects; and performing subtraction operations on custom objects. Next, observe how to perform multiplication operations on custom objects and perform floor division, modulo, and power-of operations. Then study learn built-in functions to work with custom data types; learn to execute for-loops on custom data types; and learn about properties on classes for intuitive use. Learn about properties using a simpler syntax; work with class methods to access and update class state; work with utility methods on classes; and learn how to use the abstract method to make classes that are not instantiable base classes. Finally, learners will be shown special methods and what they represent; learn to define a class and create a property within it; and observe how to differentiate between class methods and static methods.

Description:
In this 12-video course, learners will discover how to implement inheritance by using Python classes and explore coding examples of concepts such as base classes, derived classes, overriding methods, and polymorphism. Key concepts covered in this course include the default base class for all Python classes; how to model an is-a relationship by using inheritance; and how to invoke base class methods from subclasses. Next, you will observe how to define implementations for base class methods; learn to work with superclass and subclass hierarchies; and learn to define methods in a subclass and the idea of subclasses having additional attributes. Continue by learning about multiple inheritance levels in classes; multiple base classes for a single subclass; and polymorphism, an important characteristic of objects in object-oriented programming. Then you will learn to implement polymorphism in Python; learn about class inheritance and polymorphism; and learn to implement base and derived classes. Finally, learn to specify an init method to initialize member variables; learn about getters and setters for member variables; and learn to override a method.

Description:
Explore implementations of Python classes, methods, and instance and class variables in this 15-video course. Learn how to implement private variables in Python classes and program problems with classes. Key concepts covered here include how to create classes by using Python; how to assign attributes to objects of classes; and how to initialize class variables by using the init special method. Next, you will observe how to initialize values for a class when you create objects; how to pass arguments to initialize the state of a class object; and additional methods in a class, as well as how class variables work. Learners will examine how class variables are different from instance variables and how class variables share memory across objects of a class; and work with variables that have their own memory in each object. Then examine getters and setters for each instance variable; learn to prevent inadvertent modification of instance variables; and learn to create a class to represent a real-world entity. Finally, observe how to parse information to create classes with a dictionary.

Description:
In this 7-video course, learners will explore the concept of logical units, such as classes, and how they are used to hold state and behavior. Examine the modeling of is-a relationships by using inheritance and the advantages of object-oriented programming. You will begin with an introduction to classes, which are an integral part of Python programming. In this first tutorial, learn how state and behavior can be encapsulated in a single unit. This leads learners to examine how classes can be used as blueprints to create objects, and then to compare objects and instances to classes. Following on from this, you will take a look at inheritance, and model is-a relationship using inheritance. In the final tutorial in this course, you will explore the advantages of using object-oriented programming. In the concluding exercise, you will be asked to describe classes, define how state and behavior of a class are represented, list characteristics of class objects or instances, describe class inheritance, and list advantages of object-oriented programing with classes.
