### Outras funções de utilidade { #other-utility-functions }

Qualquer outra função de utilidade que você chame diretamente pode ser criada com `def` normal ou `async def` e o FastAPI não irá afetar o modo como você a chama.

### Other utility functions { #other-utility-functions }

Any other utility function that you call directly can be created with normal `def` or `async def` and FastAPI won't affect the way you call it.

### Otras funciones de utilidad { #other-utility-functions }

Cualquier otra función de utilidad que llames directamente puede ser creada con `def` normal o `async def` y FastAPI no afectará la forma en que la llames.
