Perceba que isso significa que "`one_person` é uma **instância** da classe `Person`".

Isso não significa que "`one_person` é a **classe** chamada `Person`".

## Modelos Pydantic

O <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> é uma biblioteca Python para executar a validação de dados.

Para fazer isso, use a dica de tipo padrão do Python <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:

/// note

import java.io.IOException;
import java.io.PrintWriter;
import java.io.StringWriter;

import jcifs.smb1.smb1.WinError;
import jcifs.smb1.util.Hexdump;

/**
 * DCE/RPC exception class for SMB1 compatibility
 */
public class DcerpcException extends IOException implements DcerpcError, WinError {

    static String getMessageByDcerpcError(final int errcode) {
        int min = 0;
        int max = DCERPC_FAULT_CODES.length;

<img src="/img/python-types/image06.png">

Merk op dat dit betekent dat "`one_person` een **instantie** is van de klasse `Person`".

Dit betekent niet dat `one_person` de **klasse** is met de naam `Person`.
