Pickling is the process of preserving or extending the lifespan of food. The resulting food is called a pickle, and to prevent ambiguity, prefaced with the 'pickled' adjective. text/html 2023-11-05T20:34:25+00:00 Anonymous (anonymous@undisclosed.example.com) https://miguelangel.torresegea.es/wiki/info:cursos:pue:python-pcpp1:m1:3.1?rev=1699216465&do=diff 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/html 2023-11-05T20:35:05+00:00 Anonymous (anonymous@undisclosed.example.com) https://miguelangel.torresegea.es/wiki/info:cursos:pue:python-pcpp1:m1:4.3?rev=1699216505&do=diff 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. text/html 2023-11-05T20:33:38+00:00 Anonymous (anonymous@undisclosed.example.com) https://miguelangel.torresegea.es/wiki/info:cursos:pue:python-pcpp1:m1:2.6?rev=1699216418&do=diff 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/html 2023-11-05T20:32:21+00:00 Anonymous (anonymous@undisclosed.example.com) https://miguelangel.torresegea.es/wiki/info:cursos:pue:python-pcpp1:m1:2.1?rev=1699216341&do=diff 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/html 2023-11-05T20:32:38+00:00 Anonymous (anonymous@undisclosed.example.com) https://miguelangel.torresegea.es/wiki/info:cursos:pue:python-pcpp1:m1:2.2?rev=1699216358&do=diff 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/html 2023-11-05T20:32:53+00:00 Anonymous (anonymous@undisclosed.example.com) https://miguelangel.torresegea.es/wiki/info:cursos:pue:python-pcpp1:m1:2.3?rev=1699216373&do=diff 2.3 Extended function argument syntax When we talk about function arguments, we should recall the following facts: * some functions can be invoked without arguments; * 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;
