Calculator Agent

A simple AI-powered calculator agent built with LangChain and LangGraph. The agent can perform basic arithmetic operations (addition, subtraction, multiplication, division) by interpreting natural language instructions.

Features

• Performs sequential arithmetic operations based on user queries.
• Uses OpenAI's GPT-4 for reasoning and tool calling.
• Handles errors gracefully (e.g., division by zero).

Requirements

• Python 3.8+
• OpenAI API keys

Installation

1. Clone or download the repository.
2. Install dependencies:

   pip install langchain-openai langgraph python-dotenv
   

3. Create a .env file in the project root and add your OpenAI API key:

   OPENAI_API_KEY=your_openai_api_key_here
   

Usage

Run the example script:

python User.py

This will execute a sample arithmetic sequence and print the results.

Files

• calculator_agent.py: Defines the agent, tools, and graph.
• User.py: Example usage script.

How It Works

The agent uses LangGraph to manage a conversation flow:

• Receives a user query.
• Calls appropriate arithmetic tools.
• Returns the final result.
