Örneğin, [bir dosyayı okumak için `with` kullanabilirsiniz](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

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

Temelde `open("./somefile.txt")`, "Context Manager" olarak adlandırılan bir nesne oluşturur.

`with` bloğu bittiğinde, exception olsa bile dosyanın kapatılmasını garanti eder.

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».

Коли блок `with` завершується, він гарантує закриття файлу, навіть якщо були винятки.
