## Introduction

Strands Agents SDK-Python is a simple yet powerful Python SDK that takes a model-driven approach to building and running AI agents. From simple conversational assistants to complex autonomous workflows, Strands Agents scales with your needs, supporting both local development and production deployment. It provides a flexible and lightweight framework for creating intelligent agents with just a few lines of code.

## Installation

To get started with Strands Agents SDK-Python, ensure you have Python 3.10+ installed. Then, follow these steps:

bash
# Create and activate virtual environment
python -m venv .venv
source .venv/bin/activate  # On Windows use: .venv\Scripts\activate

# Install Strands and tools
pip install strands-agents strands-agents-tools


## Examples

Here's a quick example to demonstrate how to create a simple agent with a calculator tool:

python
from strands import Agent
from strands_tools import calculator
agent = Agent(tools=[calculator])
agent("What is the square root of 1764")


**Building Python-Based Tools:**

Easily define custom tools using Python decorators:

python
from strands import Agent, tool

@tool
def word_count(text: str) -> int:
    """Count words in text.

    This docstring is used by the LLM to understand the tool's purpose.
    """
    return len(text.split())

agent = Agent(tools=[word_count])
response = agent("How many words are in this sentence?")
