2.6 Abstract classes
Python is considered to be a very flexible programming language, but that doesn’t mean that there are no controls to impose a set of functionalities or an order in a class hierarchy. When you develop a system in a group of programmers, it would be useful to have some means of establishing requirements for classes in matters of interfaces (methods) exposed by each class.text/html2023-11-05T20:34:35+00:00Anonymous (anonymous@undisclosed.example.com)4.1 Shallow and deep copy operations

4.1 Shallow and deep copy operations
Copying objects using shallow and deep operations
In this module, you’ll learn how to copy Python objects. Specifically, you'll learn about:
* object: label vs. identity vs. value;
* the id() function and the is operand;text/html2023-11-05T20:32:38+00:00Anonymous (anonymous@undisclosed.example.com)2.2 Inheritance and polymorphism — Inheritance as a pillar of OOP

2.2 Inheritance and polymorphism — Inheritance as a pillar of OOP
Inheritance is one of the fundamental concepts of object oriented programming, and expresses the fundamental relationships between classes: superclasses (parents) and their subclasses (descendants). Inheritance creates a class hierarchy. Any object bound to a specific level of class hierarchy inherits all the traits (methods and attributes) defined inside any of the superclasses.text/html2023-11-05T20:33:26+00:00Anonymous (anonymous@undisclosed.example.com)2.5 Different faces of Python methods

2.5 Different faces of Python methods
Until now, we’ve been implementing methods that have performed operations on the instances (objects), and in particular the attributes of the instance, so we’ve called them instance methods.
The instance methods, as the first parameter, take thetext/html2023-11-05T20:34:13+00:00Anonymous (anonymous@undisclosed.example.com)2.9 Inheriting properties from built-in classes

2.9 Inheriting properties from built-in classes
Python gives you the ability to create a class that inherits properties from any Python built-in class in order to get a new class that can enrich the parent's attributes or methods. As a result, your newly-created class has the advantage of all of the well-known functionalities inherited from its parent or even parents and you can still access those attributes and methods.text/html2023-11-05T20:32:21+00:00Anonymous (anonymous@undisclosed.example.com)2.1 Python core syntax

2.1 Python core syntax
So far we have been using Python core operations that allow us to operate on strings, lists, integers, and floats. It’s natural for us to formulate expressions using algebraic symbols representing operators, or to get a number of elements in a sequence or dictionary.text/html2023-11-05T20:34:25+00:00Anonymous (anonymous@undisclosed.example.com)3.1 Advanced techniques of creating and serving exceptions

3.1 Advanced techniques of creating and serving exceptions
In this module, we'll talk about Python exceptions – objects that represent errors which occur during the execution of a program that disrupts the normal flow of the program's instructions.text/html2023-11-06T09:03:06+00:00Anonymous (anonymous@undisclosed.example.com)5.1 Metaprogramming

5.1 Metaprogramming
Introduction to metaclasses
Metaprogramming is a programming technique in which computer programs have the ability to modify their own or other programs’ codes. It may sound like an idea from a science fiction story, but the idea was born and implemented in the early 1960s.text/html2023-11-05T20:33:49+00:00Anonymous (anonymous@undisclosed.example.com)2.7 Encapsulation

2.7 Encapsulation
Attribute encapsulation
Encapsulation is one of the fundamental concepts in object-oriented programming (amongst inheritance, polymorphism, and abstraction). It describes the idea of bundling attributes and methods that work on those attributes within a class.
