Swagger UI (that provides the `/docs` interface) has better support for the
            OpenAPI-specific examples than the JSON Schema `examples`, that's the main
            use case for this.

<summary><code>uvicorn main:app --reload</code> əmri haqqında...</summary>

`uvicorn main:app` əmri aşağıdakılara instinad edir:

* `main`: `main.py` faylı (yəni Python "modulu").
* `app`: `main.py` faylında `app = FastAPI()` sətrində yaratdığımız `FastAPI` obyektidir.

The defaults that will be compiled into a main package
are reported by the command:

{{raw `
	go list -f '{{.DefaultGODEBUG}}' my/main/package
`}}

Only differences from the base Go toolchain defaults are reported.

When testing a package, `//go:debug` lines in the `*_test.go`
files are treated as directives for the test's main package.

     * one specific module. Used for compilation and execution among others.
     *
     * <h4>Context-sensitive interpretation</h4>
     * This path type makes sense only when a main module is added on the module-path by another dependency.
     * In no main module is found, the patch dependency may be added on the class-path or module-path
     * depending on whether {@link #CLASSES} or {@link #MODULES} is present.
     *

/// note | "備考"

`uvicorn main:app`は以下を示します:

* `main`: `main.py`ファイル (Python "module")。
* `app`:  `main.py`内部で作られるobject（`app = FastAPI()`のように記述される）。
* `--reload`: コードの変更時にサーバーを再起動させる。開発用。
