Apenas o código anterior à declaração com `yield` e o código contendo essa declaração são executados antes de criar uma resposta:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[2:4] *}

O valor gerado (yielded) é o que é injetado nas *operações de rota* e outras dependências:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[4] *}

O código após o `yield` é executado após a resposta:

Only the code prior to and including the `yield` statement is executed before creating a response:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[2:4] *}

The yielded value is what is injected into *path operations* and other dependencies:
