basemodel
Domain: Validation Typing
🎯 Motivation
BaseModel is the base class in pydantic that gives any class automatic validation, serialization, and parsing. Inheriting from it transforms a plain data class into a robust, self-checking model.
📋 Concrete Example
class Product(BaseModel): name: str; price: float gives you Product(name="Pen", price=1.99).model_dump() which returns {"name": "Pen", "price": 1.99} as a dict.
🔗 Analogy
BaseModel is like a mold for casting metal parts. Pour in raw material (data), and the mold guarantees every part comes out in the right shape with no defects.
