• A small course to explain metaprogramming in Python.
• This has been prepared for a 1,5h workshop and shared for everyone interested.

Explained in Markdown to allow a conversion to mindmap using Markmap. Each chapter will have code snippets under "workshop" folder to explain with examples.

• Python 3.10
• Jupyter Notebook (pip3 install notebook)
• (optional) MarkDown with VSCode+Markmap

• Introduction
  • What is a Class
  • Meta vs Hierarchy
  • type function
• Decorators
  • The making of
  • Real world examples
• Metaclasses
  • Do you need them?
  • Real world examples (don't loose them)

• Meta == Greek word for "beyond"
• Metadata == data about data
• Metaprogramming == programs that manipulate programs

• string
• A function
• A class definition
• An instance of a class
• Everything

• Object that creates a new object, or instance
• Contains functions and attributes
• Can create an instance
• Who creates a class?
  • See the workshop

• A class can inherit another
  • Can use all attributes and functions of the base/super class
  • In python any Class is always a derived class, at least of the superclass 'object'
    • See the workshop
• Multiple inheritance is possible
  • the search for attributes inherited from a parent class goes depth-first, left-to-right, not searching twice

• How classes and instances are created
• How inheritance work
• What is type

• Let's do a trip
• From the concept
• Through decorator construction
• Until real examples
• Workshop
  • The making of a decorator
  • Real world examples

• Do we need them?
• Real world examples
