Fluent Python: Implementing intuitive and productive APIs

Fluent Python: Implementing intuitive and productive APIs

November 12, 2019

Python is so consistent that we can often infer the behavior of new objects by assuming they work like the built-ins. The Python data model is the foundation of this consistent behavior. Luciano Ramalho explores the construction of Pythonic objects: classes that feel "natural" to a Python programmer and leverage some of the best language features by implementing key protocols of the data model.
