Anonymous (anonymous@undisclosed.example.com) — 2024-03-04T12:24:39+00:00

4.1 Logging in Python Logging in Python The Python Standard Library provides a useful module called logging to log events occurring in the application. Logs are most often used to find the cause of an error. By default, Python and its modules provide many logs informing you of the causes of errors. However, it's good practice to create your own logs that may be useful to you or other programmers.

All events come to the event manager, which is responsible for dispatching them to all the application components. This also means that some of the events may launch some of your callbacks, which makes you responsible for preparing the proper reactions to the user’s actions.

Anonymous (anonymous@undisclosed.example.com) — 2023-11-05T20:32:38+00:00

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.

2.8 Composition vs Inheritance - two ways to the same destination

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.

	*  some functions can be invoked without arguments;

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.
