«Менеджери контексту» - це будь-які Python-об'єкти, які можна використовувати в операторі `with`.

Наприклад, [можна використати `with`, щоб прочитати файл](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Під капотом `open("./somefile.txt")` створює об'єкт, який називається «Менеджер контексту».
