## Context Managers { #context-managers }

### What are "Context Managers" { #what-are-context-managers }

"Context Managers" are any of those Python objects that you can use in a `with` statement.

```

Internamente, `open("./somefile.txt")` crea un objeto llamado "Context Manager".

Cuando el bloque `with` termina, se asegura de cerrar el archivo, incluso si hubo excepciones.

Cuando creas una dependencia con `yield`, **FastAPI** creará internamente un context manager para ella y lo combinará con algunas otras herramientas relacionadas.

One of those distributed container management systems like Kubernetes normally has some integrated way of handling...
