Unlocking Python's Core Magic
.ical
2024-09-28 –, 4F Track4

Discover the hidden gems of Python that can significantly improve your coding skills. While fundamental concepts such as dunder methods, decorators, and iterable protocols are well-known to most Python developers, not everyone knows how to apply them. In this presentation, you will learn how these features work and see their application in real-world open-source projects.

This presentation briefly introduces a few of Python's fundamental concepts. The objective of this talk is not to extensively cover the details of these mechanisms but to demonstrate how these concepts can be applied to a real-world open-source project. The following concepts will be covered.

  1. dunder method
  2. __getattr__ and PEP 562
  3. decorators
  4. functool.partial
  5. Iterable Protocol
Why did you choose this topic? –

Even though most Python developers are familiar with these concepts, they may not use them frequently during implementation and might forget about them. By demonstrating how they are used in an open-source project, I want to showcase how they can be applied to real-world use cases and how powerful they can be.
