Attributes
The Dataset has many attributes, like features, num_columns, and shape:
dataset.features, dataset.num_columns, dataset.shape
Output
({'sentence': Value(dtype='string', id=None),
'source': Value(dtype='string', id=None)},
2,
(3852, 2))
Our dataset has two columns, sentence and source, and there are 3,852 sentences
in it.
It can be indexed like a list:
dataset[2]
Output
{'sentence': 'There was nothing so VERY remarkable in that; nor did
Alice think it so VERY much out of the way to hear the Rabbit say to
itself, `Oh dear!',
'source': 'alice28-1476.txt'}
That’s the third sentence in our dataset, and it is from Alice’s Adventures in
Wonderland.
And its columns can be accessed as a dictionary too:
dataset['source'][:3]
Output
['alice28-1476.txt', 'alice28-1476.txt', 'alice28-1476.txt']
