2.3 Extended function argument syntax
When we talk about function arguments, we should recall the following facts:

* functions may require a specific number of arguments with no exclusions; we have to pass a required number of arguments in an imposed order to follow function definition;text/html2023-11-05T20:33:26+00:00Anonymous (anonymous@undisclosed.example.com)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.

4.1 PEP 257 – Docstring Conventions
What is PEP 257?
PEP 257 is a document created as part of the Python Developer's Guide, which makes an attempt to standardize the high-level structure of docstrings. It outlines the conventions, best practices, and semantics (not laws or regulations!) associated with documenting Python code using docstrings. In short, it tries to answer the following two questions:text/html2023-12-22T11:20:26+00:00Anonymous (anonymous@undisclosed.example.com)Python Professional Course Series: GUI Programming

1.6 Events and how to handle them
Event handling
As you already know, events are the fuel which propel the application’s movements. 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.text/html2023-11-05T20:33:07+00:00Anonymous (anonymous@undisclosed.example.com)2.4 Decorators

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/html2023-12-13T22:19:41+00:00Anonymous (anonymous@undisclosed.example.com)3.1 PEP 8 – Introduction
