Creating a structured output
Structured outputs are key to extracting consistent outputs from Large Language Models, which is crucial in lots of applications.
Here, you'll use the pydantic library to define the properties that describe a Character in Romeo and Juliet via a Character class. In the next exercise, you'll use this to extract characters as structured outputs from a section of the play.
This exercise is part of the course
Graph RAG with LangChain and Neo4j
Exercise instructions
- Create a
Characterclass that extends from the appropriatepydanticbase class. - Define the
nameproperty of the class. - Define an optional
familyproperty to account for characters whose family may be unknown.

from pydantic import BaseModel, Field
from typing import Optional
# Inherit the correct pydantic class
class Character(____):
# Describe the name property
name: str = ____("The full name of the character")
# Set family to optional
____: Optional[str] = Field("The name of the family they belong to")
