## Проверка в действии { #try-it }

Если ваш файл называется `main.py`, то запустите приложение командой:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

```

</div>

/// note

The command `uvicorn main:app` refers to:

* `main`: the file `main.py` (the Python "module").
* `app`: the object created inside of `main.py` with the line `app = FastAPI()`.

It is equivalent to:

```Python
from main import app
```

///

    unixScriptTemplate.from(layout.projectDirectory.file("../../../platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt"))
    windowsScriptTemplate.from(layout.projectDirectory.file("../../../platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/windowsStartScript.txt"))
}

configurations {
    create("gradleScriptsElements") {

        #  you should specify the map of included schemas.
        #  Additional schemas have original settings apart from the main schema.
        #  The settings are objectTypeTargetList, tableExceptList,
        #  tableTargetList, and columnExceptMap.
        #  They have the same specification as ones of the main schema.
        #  Elements of this map are as below: 
        #    o objectTypeTargetList: (NotRequired - Default 'map:{TABLE;VIEW}')

All the code blocks can be copied and used directly (they are actually tested Python files).

To run any of the examples, copy the code to a file `main.py`, and start `fastapi dev` with:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting development server 🚀

Sie könnten beispielsweise eine Datei `config.py` haben mit:

{* ../../docs_src/settings/app01_py39/config.py *}

Und dann verwenden Sie diese in einer Datei `main.py`:

{* ../../docs_src/settings/app01_py39/main.py hl[3,11:13] *}
