    This operator creates a batched reader which combines the data from the
    input reader to batched data.

    Args:
        reader(generator): the data reader to read from.
        batch_size(int): size of each mini-batch.
        drop_last(bool, optional): If set to True, the last batch is dropped when
            the size of last batch is not equal to batch_size, if set to False,
            it will not. Default: False.
    Returns:
        The batched reader.

    Return Type:
        generator

    Examples:
        .. code-block:: python

            >>> import paddle
            >>> def reader():
            ...     for i in range(10):
            ...         yield i
            >>> batch_reader = paddle.batch(reader, batch_size=2)

            >>> for data in batch_reader():
            ...     print(data)
            ...
            [0, 1]
            [2, 3]
            [4, 5]
            [6, 7]
            [8, 9]
