Pydanticモデルのようなオブジェクトを受け取り、JSON互換版を返します:

{* ../../docs_src/encoder/tutorial001_py310.py hl[4,21] *}

この例では、Pydanticモデルを`dict`に、`datetime`を`str`に変換します。

呼び出した結果は、Pythonの標準の[`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps)でエンコードできるものです。

これはJSON形式のデータを含む大きな`str`を（文字列として）返しません。JSONと互換性のある値とサブの値を持つPython標準のデータ構造（例：`dict`）を返します。

goroutine labels set through the the `runtime/pprof` package. Setting `tracebacklabels=1`
includes these key/value pairs in the goroutine status header of runtime
tracebacks and debug=2 runtime/pprof stack dumps. This format may change in the future.

Go 1.26 added a new `cryptocustomrand` setting that controls whether most crypto/...
APIs ignore the random `io.Reader` parameter. For Go 1.26, it defaults

Результатом её вызова является объект, который может быть закодирован с помощью функции из стандартной библиотеки Python – [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps).

In diesem Beispiel wird das Pydantic-Modell in ein `dict`, und das `datetime`-Objekt in ein `str` konvertiert.

Das Resultat dieses Aufrufs ist etwas, das mit Pythons Standard-[`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps) kodiert werden kann.

En este ejemplo, convertiría el modelo de Pydantic a un `dict`, y el `datetime` a un `str`.

El resultado de llamarlo es algo que puede ser codificado con la función estándar de Python [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps).

Bu örnekte, Pydantic model'i bir `dict`'e, `datetime`'ı da bir `str`'e dönüştürür.

Bu fonksiyonun çağrılmasıyla elde edilen sonuç, Python standardındaki [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps) ile encode edilebilecek bir şeydir.

In this example, it would convert the Pydantic model to a `dict`, and the `datetime` to a `str`.

The result of calling it is something that can be encoded with the Python standard [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps).

It doesn't return a large `str` containing the data in JSON format (as a string). It returns a Python standard data structure (e.g. a `dict`) with values and sub-values that are all compatible with JSON.
