Chapter 5: Metaprogramming and Dynamic Code in Python

Metaprogramming in Python provides developers with powerful tools to dynamically manipulate and generate classes and their behaviors at runtime. Essential techniques include utilizing metaclasses, dynamically creating methods and attributes, and leveraging the built-in type function for class generation. Although metaprogramming simplifies coding and enables the creation of advanced frameworks, it requires careful application to maintain code readability.
