/// note | Nota

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

  var result = STANDARD_DATE_FORMAT.get().parse(this, position)
  if (position.index == length) {
    // STANDARD_DATE_FORMAT must match exactly; all text must be consumed, e.g. no ignored
    // non-standard trailing "+01:00". Those cases are covered below.
    return result
  }
  synchronized(BROWSER_COMPATIBLE_DATE_FORMAT_STRINGS) {
    for (i in 0 until BROWSER_COMPATIBLE_DATE_FORMAT_STRINGS.size) {

import uvicorn
from fastapi import FastAPI

app = FastAPI()


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


if __name__ == "__main__":

  private static final double[] VALUES = {
    Double.NEGATIVE_INFINITY,
    -Double.MAX_VALUE,
    (double) Long.MIN_VALUE,
    (double) Integer.MIN_VALUE,
    -Math.PI,
    -1.0,
    -Double.MIN_VALUE,
    -0.0,
    +0.0,
    Double.MIN_VALUE,
    1.0,
    Math.PI,
    (double) Integer.MAX_VALUE,
    (double) Long.MAX_VALUE,
    Double.MAX_VALUE,
    Double.POSITIVE_INFINITY,
    Double.NaN,
    Float.MAX_VALUE,
  };

```

</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
