### Walidacja

* Walidacja większości (lub wszystkich?) **typów danych** Pythona, w tym:
    * Obiektów JSON (`dict`).
    * Tablic JSON (`list`) ze zdefiniowanym typem elementów.
    * Pól tekstowych (`str`) z określeniem minimalnej i maksymalnej długości.
    * Liczb (`int`, `float`) z wartościami minimalnymi, maksymalnymi, itp.

* Walidacja bardziej egzotycznych typów danych, takich jak:
    * URL.

            .build();
    cache.put(1, 1);
    ticker.advance(10, MINUTES);
    cache.invalidateAll();

Mas se você tem certeza que o conteúdo que você está retornando é **serializável com JSON**, você pode passá-lo diretamente para a classe de resposta e evitar o trabalho extra que o FastAPI teria ao passar o conteúdo pelo `jsonable_encoder` antes de passar para a classe de resposta.

Você pode criar e utilizar variáveis de ambiente no terminal, sem precisar utilizar Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console

			})
		if err != nil {
			t.Fatalf("Erasure Object upload failed: <ERROR> %s", err)
		}
		versions[i] = objInfo.VersionID
	}

	// Remove and check the version in the second pool, then
	// remove and check the version in the first pool
	for testIdx, vid := range []string{versions[1], versions[0]} {
		names := []ObjectToDelete{
			{
				ObjectV: ObjectV{
					ObjectName: objectName,
					VersionID:  vid,
				},
