- Python Core (language, stdlib, etc.)
Description
Descriptors and metaclasses are advanced Python features. While it is
possible to write Python programs without active knowledge of them,
knowing more about them facilitates a deeper understanding of
the language. With examples, you will learn how they work and how to
write your own descriptors and metaclasses. Furthermore, you will understand
when to use and when better not to use them.
Abstract
This tutorial is a systematic introduction to descriptors and metaclasses.
It covers all relevant information with a focus on practical applications
for common tasks.
In hand-on sessions you will learn how to write your own descriptors that
adapt attribute access to your needs. You will experience how metaclasses
can help you to get more insight into a code base.
Use cases provide working code that can serve as a basis for your own
solutions. You will gain a deeper understanding of more advanced concepts
that can help to write better programs.
I've been delivering these topics over the last years as a part of an advanced
training in open and in-house courses as well as trainings at EuroPython,
PyCon PL, PyCon DE and PyCon IE. The material has been continuously refined
owing to the participant feedback.
