```python
from main import app
```

Якщо ваш код має таку структуру:

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

Тоді ви встановили б `entrypoint` як:

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

що еквівалентно:

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

```console
// Here we don't set the env var yet
$ python main.py

// As we didn't set the env var, we get the default value

Hello World from Python

// But if we create an environment variable first
$ export MY_NAME="Wade Wilson"

// And then call the program again
$ python main.py

// Now it can read the environment variable

Hello Wade Wilson from Python
```

```console
// Ici, nous ne définissons pas encore la variable d'environnement
$ python main.py

// Comme nous ne l'avons pas définie, nous obtenons la valeur par défaut

Hello World from Python

// Mais si nous créons d'abord une variable d'environnement
$ export MY_NAME="Wade Wilson"

// Puis que nous relançons le programme
$ python main.py

// Il peut maintenant lire la variable d'environnement
