#### 一个随机条目 { #a-random-item }

使用 `data.items()` 我们会得到一个包含每个字典项键和值的元组的 <dfn title="可以用 for 循环迭代的对象，例如 list、set 等">可迭代对象</dfn>。

我们用 `list(data.items())` 把这个可迭代对象转换成一个真正的 `list`。

然后用 `random.choice()` 可以从该列表中获取一个**随机值**，也就是一个 `(id, name)` 的元组。它可能像 `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")` 这样。

接着我们把这个元组的**两个值**分别赋给变量 `id` 和 `name`。

所以，即使用户没有提供条目 ID，他们仍然会收到一个随机推荐。

  write_action_env_to_bazelrc('PYTHON_LIB_PATH', python_lib_path)
  write_to_bazelrc('build --python_path=\"{}"'.format(python_bin_path))
  environ_cp['PYTHON_BIN_PATH'] = python_bin_path

  # If chosen python_lib_path is from a path specified in the PYTHONPATH
  # variable, need to tell bazel to include PYTHONPATH
  if environ_cp.get('PYTHONPATH'):
    python_paths = environ_cp.get('PYTHONPATH').split(':')

            // * if the time picker is enabled, apply the hour/minute/second from the select boxes to the clicked date
            // * if autoapply is enabled, and an end date was chosen, apply the selection
            // * if single date picker mode, and time picker isn't enabled, apply the selection immediately
            // * if one of the inputs above the calendars was focused, cancel that manual input

#### ランダムなアイテム { #a-random-item }

`data.items()` で、辞書の各アイテムのキーと値を含むタプルを持つ <dfn title="for ループで繰り返し処理できるもの（list、set など）">反復可能オブジェクト</dfn> を取得します。

この反復可能オブジェクトを `list(data.items())` で適切な `list` に変換します。

そして `random.choice()` でその `list` から **ランダムな値** を取得するので、`(id, name)` のタプルを得ます。これは `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")` のようになります。

次に、そのタプルの **2つの値を代入** して、変数 `id` と `name` に入れます。

			srcInfo.Reader.Close() // We are not interested in the reader stream at this point close it.
			return srcSet.CopyObject(ctx, srcBucket, srcObject, dstBucket, dstObject, srcInfo, srcOpts, dstOpts)
		}
		// Destination is not versioned and source version ID is empty
		// perform an in-place update.
		if !dstOpts.Versioned && srcOpts.VersionID == "" {

     *
     * <p>Note that the method will be called even upon an invocation of {@code tryLock()}. Although
     * {@code tryLock()} technically recovers from deadlock by eventually timing out, this behavior
     * is chosen based on the assumption that it is the application's wish to prohibit any cyclical
     * lock acquisitions.
