By the end of this guide, your Python server will respond with translated content based on the request's language.

General Translation supports both **FastAPI** and **Flask**. Pick the guide that matches your framework:

## Overview

The Python SDK provides:

- **`t()` function** — translate any string inline, with variable interpolation
- **`derive()` function** — derive translated values from source content
- **Automatic locale detection** — parses `Accept-Language` headers out of the box
- **`gt.config.json` support** — same config file used across all GT libraries

## Quick Example

```python title="app.py"
from fastapi import FastAPI
from gt_fastapi import initialize_gt, t

app = FastAPI()
initialize_gt(app)

@app.get("/")
def index():
    return {"message": t("Hello, world!")}
```

That's it — your endpoint now returns translated content based on the request's locale.
