If you have several sentences you want to process, you can do this efficiently by sending them as a list to the
tokenizer:
```py
batch_sentences = ["Hello I'm a single sentence", "And another sentence", "And the very very last one"]
encoded_inputs = tokenizer(batch_sentences)
print(encoded_inputs)
{'input_ids': [[101, 8667, 146, 112, 182, 170, 1423, 5650, 102],
               [101, 1262, 1330, 5650, 102],
               [101, 1262, 1103, 1304, 1304, 1314, 1141, 102]],
 'token_type_ids': [[0, 0, 0, 0, 0, 0, 0, 0, 0],
                    [0, 0, 0, 0, 0],
                    [0, 0, 0, 0, 0, 0, 0, 0]],
 'attention_mask': [[1, 1, 1, 1, 1, 1, 1, 1, 1],
                    [1, 1, 1, 1, 1],
                    [1, 1, 1, 1, 1, 1, 1, 1]]}
```
We get back a dictionary once again, this time with values being lists of lists of ints.
