Você declara a "forma" dos dados como classes com atributos.

E cada atributo tem um tipo.

Em seguida, você cria uma instância dessa classe com alguns valores e ela os validará, os converterá para o tipo apropriado (se for esse o caso) e fornecerá um objeto com todos os dados.

E você recebe todo o suporte do editor com esse objeto resultante.

Um exemplo da documentação oficial do Pydantic:

        sink.writeUtf8(requestMethod).writeByte('\n'.code)
        sink.writeDecimalLong(varyHeaders.size.toLong()).writeByte('\n'.code)
        for (i in 0 until varyHeaders.size) {
          sink
            .writeUtf8(varyHeaders.name(i))
            .writeUtf8(": ")
            .writeUtf8(varyHeaders.value(i))
            .writeByte('\n'.code)
        }
