   * <p>Removals may or may not happen immediately as each element is tested against the predicate.
   * The behavior of this method is not specified if {@code predicate} is dependent on {@code
   * removeFrom}.
   *
   * <p><b>Java 8+ users:</b> if {@code removeFrom} is a {@link Collection}, use {@code
   * removeFrom.removeIf(predicate)} instead.

Claro, há alguns casos em que não há problema em executar as etapas anteriores várias vezes; nesse caso, é muito mais fácil de lidar.

Além disso, tenha em mente que, dependendo da sua configuração, em alguns casos você **pode nem precisar de nenhuma etapa anterior** antes de iniciar sua aplicação.

Nesse caso, você não precisaria se preocupar com nada disso. 🤷

os seus **projetos dependem**. Isso é muito difícil de gerenciar. E você provavelmente acabaria executando alguns projetos com algumas **versões incompatíveis** dos pacotes, e não saberia por que algo não está funcionando.

Além disso, dependendo do seu sistema operacional (por exemplo, Linux, Windows, macOS), ele pode ter vindo com o Python já instalado. E, nesse caso, provavelmente tinha alguns pacotes pré-instalados com algumas versões específicas **necessárias para o seu sistema**. Se...

### Dependencies { #dependencies }

The same applies for [dependencies](tutorial/dependencies/index.md){.internal-link target=_blank}. If a dependency is a standard `def` function instead of `async def`, it is run in the external threadpool.
