A maioria dessas configurações é variável (pode mudar), como URLs de banco de dados. E muitas podem ser sensíveis, como segredos.

Por esse motivo, é comum fornecê-las em variáveis de ambiente lidas pela aplicação.

Para entender variáveis de ambiente, você pode ler [Variáveis de Ambiente](../environment-variables.md){.internal-link target=_blank}.

## Revise Pull Requests { #review-pull-requests }

Você pode me ajudar revisando pull requests de outras pessoas.

Novamente, por favor tente ao máximo ser gentil. 🤗

Veja o que ter em mente e como revisar um pull request:

### Entenda o problema { #understand-the-problem }

                new TestStringSetGenerator() {
                  @Override
                  protected Set<String> create(String[] elements) {
                    // Put the sets in different orders for the hell of it
                    return union(
                        new LinkedHashSet<>(asList(elements[0], elements[1], elements[2])),
                        new LinkedHashSet<>(asList(elements[1], elements[0], elements[2])));

At the same point, you try to trigger the autocomplete with `Ctrl+Space` and you see:

<img src="/img/python-types/image02.png">

With that, you can scroll, seeing the options, until you find the one that "rings a bell":

<img src="/img/python-types/image03.png">

## More motivation { #more-motivation }

Check this function, it already has type hints:

{* ../../docs_src/python_types/tutorial003_py39.py hl[1] *}

В прежних версиях NodeJS/браузерного JavaScript вы бы использовали «callbacks» (обратные вызовы), что приводит к «callback hell» (ад обратных вызовов).

## Сопрограммы { #coroutines }

Exemplos de literais de string em trechos de código: `"this"`, `'that'`.

Um exemplo difícil de literais de string em trechos de código: `f"I like {'oranges' if orange else "apples"}"`

Pesado: `Yesterday, my friend wrote: "If you spell incorrectly correctly, you have spelled it incorrectly". To which I answered: "Correct, but 'incorrectly' is incorrectly not '"incorrectly"'"`
