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]
