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.

El lidiar con errores de programación tiene (al menos) dos partes. La primera es cuando te metes en problemas porque tu código, aparentemente correcto, se alimenta con datos incorrectos.

Antes de comenzar a hablar sobre la herencia, queremos presentar un nuevo y práctico mecanismo utilizado por las clases y los objetos de Python: es la forma en que el objeto puede presentarse a si mismo

1.1 Classes, Instances, Attributes, Methods — introduction

Introduction to Object-Oriented Programming

This module addresses the advanced Object Oriented Programming (OOP) issues that are at the heart of Python programming.

The object-oriented approach is an evolution of good design practices that go back to the very beginning of computer programming.

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;

1.1 What is PEP?

PEP may refer to several things:

	*  football (soccer) fans will definitely associate it with the famous ex-footballer and football manager, Josep Guardiola, whose nickname is (guess what) Pep;
	*  those who have medical jobs will surely think of post-exposure prophylaxis, which in turn has to do with taking preventive medical measures after contact with pathogens;

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 be

Cómo las computadoras entienden los caracteres individuales

Has escrito algunos programas interesantes desde que comenzó este curso, pero todos ellos han procesado solo un tipo de datos: los numéricos. Como sabes (puedes ver esto en todas partes), muchos datos de la computadora no son números: nombres, apellidos, direcciones, títulos, poemas, documentos científicos, correos electrónicos, sentencias judiciales, confesiones de amor y mucho, mucho más.

4.3 Making Python objects persistent using the shelve module

Serialization of Python objects using the shelve module

As you remember, the pickle module is used for serializing objects as a single byte stream. Both serializing and deserializing parties must abide by the order of all the elements placed into a file or database, or sent via a network.

1.7 Visiting widgets’ properties

Widget properties

As you already know, every widget has a set of properties, and the widget’s user is able to change them by modifying the widget’s appearance and behavior. We’ll show you how to manipulate properties and present a basic set of the most usable widget properties.

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.
