### 「コンテキストマネージャ」とは { #what-are-context-managers }

「コンテキストマネージャ」とは、`with`文の中で使用できるPythonオブジェクトのことです。

例えば、[ファイルを読み込むには`with`を使用することができます](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

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

その後の`open("./somefile.txt")`は「コンテキストマネージャ」と呼ばれるオブジェクトを作成します。

		combineSharedBlocks := make(map[int][]byte)
		combineFilledBlocks := make(map[int][]byte)
	nextFile:
		for key, file := range files[partIdx] {
			fmt.Println("Reading base version", file[0], "part", part)
			var combined []byte
			var missingAll int
			var lastValidAll int

			attempt := 0
			for block := 0; ; block++ {
				combineFilled := combineFilledBlocks[block]
