## 컨텍스트 관리자

### "컨텍스트 관리자"란?

"컨텍스트 관리자"는 Python에서 `with` 문에서 사용할 수 있는 모든 객체를 의미합니다.

예를 들어, <a href="https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files" class="external-link" target="_blank"> `with`를 사용하여 파일을 읽을 수 있습니다</a>:

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