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** — the same config file used across all GT libraries

## Quick example

First, create a `gt.config.json` in your project root:

```json title="gt.config.json"
{
  "projectId": "your-project-id",
  "defaultLocale": "en",
  "locales": ["es", "fr"]
}
```

Then set up your app:

```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!")}
```

Then translate and publish your content:

```bash
pip install gtx-cli
gt translate --publish
```

That&#39;s it — your endpoint now returns translated content based on the request&#39;s locale.
