Python Development (3.14+)

Core Philosophy

1. Stdlib and Mature Libraries First

   • Always prefer Python stdlib solutions
   • External deps only when stdlib insufficient
   • Prefer dataclasses over attrs, pathlib over os.path

2. Type Hints Everywhere (No Any)

   • Python 3.14 has lazy annotations by default
   • Use Protocol for structural typing (duck typing)
   • Avoid Any—use concrete types or generics

3. Protocol Over ABC

   • Protocol for implicit interface satisfaction
   • ABC only when runtime isinstance() needed
   • Protocols are more flexible and Pythonic
