</div>

alors la variable interne `__name__` de votre fichier, créée automatiquement par Python, aura pour valeur la chaîne de caractères `"__main__"`.

Ainsi, la section :

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

va s'exécuter.

---

Cela ne se produira pas si vous importez ce module (fichier).

Par exemple, si vous avez un autre fichier `importer.py` qui contient :

```Python

```

</div>

então a variável interna `__name__` no seu arquivo, criada automaticamente pelo Python, terá como valor a string `"__main__"`.

Então, a seção:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

vai executar.

---

Isso não acontecerá se você importar esse módulo (arquivo).

Então, se você tiver outro arquivo `importer.py` com:

```Python
from myapp import app

\u0009 => \u0020
\u000A => \u0020
\u000B => \u0020
\u000C => \u0020
\u000D => \u0020
\u001C => \u0020
\u001D => \u0020
\u001E => \u0020
\u001F => \u0020
\u00A0 => \u0020
\u1680 => \u0020
\u180E => \u0020
\u2000 => \u0020
\u2001 => \u0020
\u2002 => \u0020
\u2003 => \u0020
\u2004 => \u0020
\u2005 => \u0020
\u2006 => \u0020
\u2007 => \u0020
\u2008 => \u0020
\u2009 => \u0020
\u200A => \u0020
\u200B => \u0020

```

</div>

dann hat in Ihrer Datei die interne Variable `__name__`, die von Python automatisch erstellt wird, als Wert den String `"__main__"`.

Daher wird der Abschnitt:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

ausgeführt.

---

Dies wird nicht passieren, wenn Sie das Modul (die Datei) importieren.

Wenn Sie also eine weitere Datei `importer.py` mit folgendem Inhalt haben:

```Python

import uvicorn
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def root():
    a = "a"
    b = "b" + a
    return {"hello world": b}


if __name__ == "__main__":
