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/html2023-12-28T18:35:52+00:00Anonymous (anonymous@undisclosed.example.com)1.8 Interacting with widget methods

1.8 Interacting with widget methods
Widget methods
Widgets have methods – you’ve met some of them already. Now we’re going to show you a few more of them, and we’ll start with two which seem to be very specific.

What is GUI?
GUI is an acronym. Moreover, it’s a three-letter acronym, a representative of a well-known class of acronyms which plays a very important role in the IT industry.

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/html2023-12-28T18:48:25+00:00Anonymous (anonymous@undisclosed.example.com)1.9 Looking at variables

1.9 Looking at variables
Variables
To implement some of its functions, Tkinter uses a very special kind of variable called an observable variable. This variable works like a regular variable (i.e., it’s able to store values which are accessible to the outside world) but there is something more – any change of the variable’s state can betext/html2023-12-28T19:51:18+00:00Anonymous (anonymous@undisclosed.example.com)2.3 A small lexicon of widgets - Part 3

What is a database?
Nowadays, social applications such as Facebook, Twitter, and Instagram are very popular. Every day many people create new accounts, and existing users add or share different content. You’ve surely noticed that the data sent to those applications are still available after a few days, or even years. Do you know how that’s possible?
