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)
