## 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)
```

			return
		}
		switch msgp.UnsafeString(field) {
		case "Curr":
			z.Curr, err = dc.ReadInt()
			if err != nil {
				err = msgp.WrapError(err, "Curr")
				return
			}
		case "Avg":
			z.Avg, err = dc.ReadFloat32()
			if err != nil {
				err = msgp.WrapError(err, "Avg")
				return
			}
		case "Max":
			z.Max, err = dc.ReadInt()
			if err != nil {
				err = msgp.WrapError(err, "Max")
				return
			}

			continue
		}
		ekvs = append(ekvs, ekv)
	}
	if err = scanner.Err(); err != nil {
		return nil, err
	}
	return ekvs, nil
}
