From `typing`, import `List` (with a capital `L`):

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial006.py!}
```

Declare the variable, with the same colon (`:`) syntax.

As the type, put the `List` that you imported from `typing`.

	var b strings.Builder
	l := len(camel)
	for i, v := range camel {
		// A is 65, a is 97
		if v >= 'a' {
			b.WriteRune(v)
			continue
		}
		// v is capital letter here
		// disregard first letter
		// add underscore if last letter is capital letter
		// add underscore when previous letter is lowercase
		// add underscore when next letter is lowercase
		if (i != 0 || i == l-1) && ((i > 0 && rune(camel[i-1]) >= 'a') ||

En particular, cuando corras en **Kubernetes** probablemente **no** querrás usar workers y en cambio correr **un solo proceso de Uvicorn por contenedor**, pero te contaré sobre eso más adelante en ese capítulo.

## Múltiples Workers

Em particular, ao executar no **Kubernetes** você provavelmente **não** vai querer usar vários trabalhadores e, em vez disso, executar **um único processo Uvicorn por contêiner**, mas falarei sobre isso mais adiante neste capítulo.
