Un **context manager** en Python es algo que puedes usar en un statement `with`, por ejemplo, `open()` puede ser usado como un context manager:

```Python
with open("file.txt") as file:
    file.read()
```

En versiones recientes de Python, también hay un **async context manager**. Lo usarías con `async with`:

```Python
