```python
from main import app
```

Si tu código estuviera estructurado así:

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

Entonces establecerías el `entrypoint` como:

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

lo cual sería equivalente a:

```python
from backend.main import app
```

```python
from main import app
```

Si votre code était structuré comme ceci :

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

Vous définiriez alors le `entrypoint` comme suit :

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

ce qui serait équivalent à :

```python
from backend.main import app
```

```

/// note | Примечание

Команда `uvicorn main:app` означает:

* `main`: файл `main.py` (Python‑«модуль»).
* `app`: объект, созданный в `main.py` строкой `app = FastAPI()`.

Эквивалентно:

```Python
from main import app
```

/// note | Nota

O comando `uvicorn main:app` refere-se a:

* `main`: o arquivo `main.py` (o "módulo" Python).
* `app`: o objeto criado dentro de `main.py` com a linha `app = FastAPI()`.

É equivalente a:

```Python
from main import app
```
