## Feature

- 基于前缀树（PyTrie）高效快速把连续拼音切分为单字拼音列表，便于后续拼音转汉字等处理。

## Install

- Requirements and Installation

```
pip install pinyintokenizer
```

or

```
git clone https://github.com/shibing624/pinyin-tokenizer.git
cd pinyin-tokenizer
python setup.py install
```


## Usage

### 拼音切分（Pinyin Tokenizer）

example：[examples/pinyin_tokenize_demo.py](examples/pinyin_tokenize_demo.py):


```python
import sys

sys.path.append('..')
from pinyintokenizer import PinyinTokenizer

if __name__ == '__main__':
    m = PinyinTokenizer()
    print(f"{m.tokenize('wo3')}")
    print(f"{m.tokenize('nihao')}")
    print(f"{m.tokenize('lv3you2')}")  # 旅游
    print(f"{m.tokenize('liudehua')}")
    print(f"{m.tokenize('liu de hua')}")  # 刘德华
    print(f"{m.tokenize('womenzuogelvyougongnue')}")  # 我们做个旅游攻略
    print(f"{m.tokenize('xi anjiaotongdaxue')}")  # 西安交通大学

    # not support english
    print(f"{m.tokenize('good luck')}")
```

output:

```shell
(['wo'], ['3'])
(['ni', 'hao'], [])
(['lv', 'you'], ['3', '2'])
(['liu', 'de', 'hua'], [])
(['liu', 'de', 'hua'], [' ', ' '])
(['wo', 'men', 'zuo', 'ge', 'lv', 'you', 'gong', 'nue'], [])
(['xi', 'an', 'jiao', 'tong', 'da', 'xue'], [' '])
(['o', 'o', 'lu'], ['g', 'd', ' ', 'c', 'k'])
```
- `tokenize`方法返回两个结果，第一个为拼音列表，第二个为非法拼音列表。


### 连续拼音转汉字（Pinyin2Hanzi）
先使用本库[pinyintokenizer](https://pypi.org/project/pinyintokenizer/)把连续拼音切分，再使用[Pinyin2Hanzi](https://pypi.org/project/Pinyin2Hanzi/)库把拼音转汉字。

example：[examples/pinyin2hanzi_demo.py](examples/pinyin2hanzi_demo.py):


```python
import sys
from Pinyin2Hanzi import DefaultDagParams
from Pinyin2Hanzi import dag

sys.path.append('..')
from pinyintokenizer import PinyinTokenizer

dagparams = DefaultDagParams()


def pinyin2hanzi(pinyin_sentence):
    pinyin_list, _ = PinyinTokenizer().tokenize(pinyin_sentence)
    result = dag(dagparams, pinyin_list, path_num=1)
    return ''.join(result[0].path)


if __name__ == '__main__':
    print(f"{pinyin2hanzi('wo3')}")
    print(f"{pinyin2hanzi('jintianxtianqibucuo')}")
    print(f"{pinyin2hanzi('liudehua')}")
```

output:

```shell
我
今天天气不错
刘德华
```
