# Encode Inputs

## Encode Inputs

PythonRustNode

These types represent all the different kinds of input that a [Tokenizer](https://huggingface.co/docs/tokenizers/v0.13.4.rc2/en/api/tokenizer#tokenizers.Tokenizer) accepts when using `encode_batch()`.

### TextEncodeInput

`tokenizers.TextEncodeInput`

Represents a textual input for encoding. Can be either:

* A single sequence: [TextInputSequence](https://huggingface.co/docs/tokenizers/api/input-sequences#tokenizers.TextInputSequence)
* A pair of sequences:
  * A Tuple of [TextInputSequence](https://huggingface.co/docs/tokenizers/api/input-sequences#tokenizers.TextInputSequence)
  * Or a List of [TextInputSequence](https://huggingface.co/docs/tokenizers/api/input-sequences#tokenizers.TextInputSequence) of size 2

alias of `Union[str, Tuple[str, str], List[str]]`.

### PreTokenizedEncodeInput

`tokenizers.PreTokenizedEncodeInput`

Represents a pre-tokenized input for encoding. Can be either:

* A single sequence: [PreTokenizedInputSequence](https://huggingface.co/docs/tokenizers/api/input-sequences#tokenizers.PreTokenizedInputSequence)
* A pair of sequences:
  * A Tuple of [PreTokenizedInputSequence](https://huggingface.co/docs/tokenizers/api/input-sequences#tokenizers.PreTokenizedInputSequence)
  * Or a List of [PreTokenizedInputSequence](https://huggingface.co/docs/tokenizers/api/input-sequences#tokenizers.PreTokenizedInputSequence) of size 2

alias of `Union[List[str], Tuple[str], Tuple[Union[List[str], Tuple[str]], Union[List[str], Tuple[str]]], List[Union[List[str], Tuple[str]]]]`.

### EncodeInput

`tokenizers.EncodeInput`

Represents all the possible types of input for encoding. Can be:

* When `is_pretokenized=False`: [TextEncodeInput](https://huggingface.co/docs/tokenizers/api/encode-inputs#tokenizers.TextEncodeInput)
* When `is_pretokenized=True`: [PreTokenizedEncodeInput](https://huggingface.co/docs/tokenizers/api/encode-inputs#tokenizers.PreTokenizedEncodeInput)

alias of `Union[str, Tuple[str, str], List[str], Tuple[str], Tuple[Union[List[str], Tuple[str]], Union[List[str], Tuple[str]]], List[Union[List[str], Tuple[str]]]]`.
