Todo **FastAPI** está basado en estos type hints, lo que le da muchas ventajas y beneficios.

Pero, así nunca uses **FastAPI** te beneficiarás de aprender un poco sobre los type hints.

!!! note "Nota"
    Si eres un experto en Python y ya lo sabes todo sobre los type hints, salta al siguiente capítulo.

## Motivación

Comencemos con un ejemplo simple:

class EnrichedReportRenderer extends GroovyReportRenderer {
    private static acceptedChangesRegex = ~/<a href="(.+)">accepted-public-api-changes.json<\/a>/

    @Override
    void render(File htmlReportFile, RichReportData data) {
        super.render(htmlReportFile, enrichReport(data))
    }

    /**
     * This is super-hacky: this report is instantiated via {@code newInstance()}, within a different

        get() = withValidityAssertion {
            val diagnostic = firDiagnostic as KtDiagnostic

            val firDiagnosticRenderer = RootDiagnosticRendererFactory(diagnostic)
            return firDiagnosticRenderer.render(diagnostic)
        }

    override val textRanges: Collection<TextRange>
        get() = withValidityAssertion { firDiagnostic.textRanges }

    @Suppress("UNCHECKED_CAST")
    override val psi: PSI

    addFinish() {
        const finish = this.generateFinish()
        this.container.appendChild(finish)
    }

    /**
     * Animate a typed line.
     * @param {Node} line - The line element to render.
     */
    async type(line) {
        const chars = [...line.textContent];
        line.textContent = '';
        this.container.appendChild(line);

        for (let char of chars) {

    value: |
      counter: gopls/bug
      title: Gopls bug reports
      description: Stacks of bugs encountered on the gopls server.
      type: partition, histogram, stack # choose only one.

... wird die `id` angezeigt, welche dem „Kontext“-`dict` entnommen wird, welches Sie übergeben haben:

```Python
{"id": id}
```

Mit beispielsweise einer ID `42` würde das wie folgt gerendert werden:

```html
Item ID: 42
```

## Investigação

Ao usar todas as alternativas anteriores, eu tive a chance de aprender com todas elas, aproveitar ideias e combiná-las da melhor maneira que encontrei para mim e para os times de desenvolvedores com os quais trabalhava.
