Python’da **context manager**, `with` ifadesi içinde kullanabildiğiniz bir yapıdır. Örneğin `open()` bir context manager olarak kullanılabilir:

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

Python’ın güncel sürümlerinde bir de **async context manager** vardır. Bunu `async with` ile kullanırsınız:

```Python
async with lifespan(app):
    await do_stuff()
```
