　　Python包网站: https://pypi.org/

1. 繁体与简体转换(https://github.com/berniey/hanziconv.git)

pip install hanziconv

示例:

from hanziconv import HanziConv

def switch_hanzi(keyword):
    """
    汉字转换(简体<>繁体)
    :return:
    """
    simple_chinese = HanziConv.toSimplified(keyword)
    if simple_chinese == keyword:  # 简体
        tradition_chinese = HanziConv.toTraditional(keyword)
        if tradition_chinese == simple_chinese:
            return
        return tradition_chinese
    else:
        return simple_chinese

keyword = '生活'
print(switch_hanzi(keyword))

keyword = '中國'
print(switch_hanzi(keyword))

2. 汉字转拼音(https://github.com/mozillazg/python-pinyin)

pip install pypinyin

>>> from pypinyin import pinyin, lazy_pinyin, Style
>>> pinyin('中心')
[['zhōng'], ['xīn']]
>>> pinyin('中心', heteronym=True)  # 启用多音字模式
[['zhōng', 'zhòng'], ['xīn']]
>>> pinyin('中心', style=Style.FIRST_LETTER)  # 设置拼音风格
[['z'], ['x']]
>>> pinyin('中心', style=Style.TONE2, heteronym=True)
[['zho1ng', 'zho4ng'], ['xi1n']]
>>> pinyin('中心', style=Style.TONE3, heteronym=True)
[['zhong1', 'zhong4'], ['xin1']]
>>> pinyin('中心', style=Style.BOPOMOFO)  # 注音风格
[['ㄓㄨㄥ'], ['ㄒㄧㄣ']]
>>> lazy_pinyin('中心')  # 不考虑多音字的情况
['zhong', 'xin']

3. 拼音转汉字(https://github.com/someus/Pinyin2Hanzi)

pip install Pinyin2Hanzi

示例:

from Pinyin2Hanzi import DefaultHmmParams
from Pinyin2Hanzi import viterbi

hmmparams = DefaultHmmParams()

## 2个候选
result = viterbi(hmm_params=hmmparams, observations=('ni', 'zhi', 'bu', 'zhi', 'dao'), path_num = 2)
for item in result:
    print(item.score, item.path)
'''输出
1.3155294593897203e-08 ['你', '知', '不', '知', '道']
3.6677865125992192e-09 ['你', '只', '不', '知', '道']
'''

def get_similar_words(word, num=3):
    """
    获取相似词
    :param word: 单词
    :param num: 返回词汇数量
    """
    word_pinyin = lazy_pinyin(word)

    dagparams = DefaultDagParams()
    result = dag(dagparams, tuple(word_pinyin), path_num=num)
    # 拼接,去重
    words = set()
    for item in result:
        print(item.path)
        new_word = item.path[0] if len(item.path) == 1 else ''.join(item.path)
        words.add(new_word)

    similar_words = words - set([word])
    return list(similar_words)
