FastAPI supports dependencies that do some <abbr title='sometimes also called "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code", etc.'>extra steps after finishing</abbr>.

To do this, use `yield` instead of `return`, and write the extra steps (code) after.

/// tip

Make sure to use `yield` one single time per dependency.

Isso foi modificado na versão 0.110.0 para consertar o consumo de memória não controlado das exceções relançadas automaticamente sem um manipulador (erros internos do servidor), e para manter o comportamento consistente com o código Python tradicional.
