funcchain 0.1.8

🔖 write prompts as python functions

funcchain

> pip install funcchain

Introduction

funcchain is the most pythonic way of writing cognitive systems. Leveraging pydantic models as output schemas combined with langchain in the backend allows for a seamless integration of llms into your apps. It works perfect with OpenAI Functions and soon with other models using JSONFormer.

Demo

from pydantic import BaseModel, Field
from funcchain import chain


class Item(BaseModel):
    name: str = Field(description="Name of the item")
    description: str = Field(description="Description of the item")
    keywords: list[str] = Field(description="Keywords for the item")

class ShoppingList(BaseModel):
    """ List of items to buy """
    items: list[Item]
    store: str = Field(description="The store to buy the items from")

class TodoList(BaseModel):
    todos: list[Item]
    urgency: int = Field(description="The urgency of all tasks (1-10)")


def extract_list(user_input: str) -> TodoList | ShoppingList:
    """
    The user input is either a shopping List or a todo list.
    """
    return chain()


lst = extract_list(
    input("Enter your list: ")
)

if isinstance(lst, ShoppingList):
    print("Here is your Shopping List: ")
    for item in lst.items:
        print(f"{item.name}: {item.description}")
    print(f"You need to go to: {lst.store}")

if isinstance(lst, TodoList):
    print("Here is your Todo List: ")
    for item in lst.todos:
        print(f"{item.name}: {item.description}")
    print(f"Urgency: {lst.urgency}")
