Python decorators in detail

Do you know what happens every time you use the @ symbol in Python? Do you know how to implement a decorator to be customisable at decoration time or to internally store a state?

After attending this training you will be able to answer yes to all the previous questions!

The content of the session can be split in 3 main blocks:

• 1/ Some Python basic concepts
  • Scopes
  • Namespaces
  • Closures
• 2/ Implement and understand a basic decorator
• 3/ Advanced decorators
  • Generators of decorators
  • Classes as decorators
  • Decoration of classes

Requirements:

• Intermediate Python level. Attendees must have previous knowledge of Python and should be somehow familiar with the notation @ to decorate a function or class.
• Bring your own laptop with Python installed and ready to solve some coding exercises.

PS: I also delivered a talk which covers in a more graphical way the first part of the training: https://ep2015.europython.eu/conference/talks/decorators-demystified
