This folder contains sample code for the Real Python tutorial on [How to Write a CLAUDE.md File for Claude Code](https://realpython.com/python-claude-md/).
It's a single script, [bedrock_example.py](./bedrock_example.py), that you can use to follow-along the tutorial examples in your local Claude Code session.

We could add a inline metadata block to make it easy to use for people working with uv:

Suggested change
import boto3
# /// script
# requires-python = ">=3.10"
# dependencies = [
# "boto3==1.43.15",
# ]
# ///
import boto3

Should probably add a requirements.txt file as well.

config = Config(
connect_timeout=15,
read_timeout=3600,
retries={"max_attempts": 4},
)

bedrock_client = boto3.client("bedrock-runtime", config=config)

MODEL_ID = "amazon.nova-premier-v1:0"
MAX_TOKENS = 100
TEMPERATURE = 0.1

SYSTEM_PROMPT = """You are a helpful, harmless assistant.
Your task is to assist customers with any questions they may have.
"""


def query_llm(prompt: str) -> str:
system = [

]

messages = [{"role": "user", "content": [{"text": prompt}]}]
inf_params = {"maxTokens": MAX_TOKENS, "temperature": TEMPERATURE}
