- Introduction to Metaprogramming
Defining metaprogramming and its role in Python.
Understanding how metaprogramming can manipulate code and classes dynamically.
Real-world applications and use cases of metaprogramming.
- Understanding Metaclasses
What metaclasses are and why they are used.
The default metaclass in Python: type.
How metaclasses control the creation of classes.
- Creating Custom Metaclasses
The process of defining a custom metaclass.
Using metaclasses to enforce class constraints, modify class attributes, and implement singleton patterns.
The new and init methods in metaclasses.
- Metaclass Use Cases
Implementing advanced OOP patterns using metaclasses.
Examples where metaclasses provide elegant solutions (e.g., registering classes, interface enforcement, logging class creation).
- Decorators in Metaprogramming
Using function and class decorators for metaprogramming.
Dynamically modifying or enhancing functions and classes with decorators.
Building chainable decorators and understanding their execution order.
- The Descriptor Protocol
Understanding descriptors and their role in Python.
Writing custom descriptors for managing attribute access.
Using descriptors in conjunction with metaclasses and decorators.
