pypinyin

1 排序 仅按拼音首字母 排序

安装pypinyin

pip3 install pypinyin

代码

from pypinyin import lazy_pinyin

chars = ['鑫','鹭','榕','柘','珈','骅','孚','迦','瀚','濮','浔','沱','泸','恺','怡','岷','萃','兖']

chars.sort(key=lambda char: lazy_pinyin(char)[0][0])

print([lazy_pinyin(char) for char in chars])

print(chars)

结果

[['cui'], ['fu'], ['hua'], ['han'], ['jia'], ['jia'], ['kai'], ['lu'], ['lu'], ['min'], ['pu'], ['rong'], ['tuo'], ['xin'], ['xun'], ['yi'], ['yan'], ['zhe']]

['萃', '孚', '骅', '瀚', '珈', '迦', '恺', '鹭', '泸', '岷', '濮', '榕', '沱', '鑫', '浔', '怡', '兖', '柘']

按所有拼音排序

#!/usr/bin/python3

# -*- coding: UTF-8 -*-

# from __future__ import unicode_literals

from pypinyin import lazy_pinyin

def sort_pinyin(hanzi_list):

hanzi_list_pinyin=[]

hanzi_list_pinyin_alias_dict={}

for single_str in hanzi_list:

py_r = lazy_pinyin(single_str)

# print("整理下")

single_str_py=''

for py_list in py_r:

single_str_py=single_str_py+py_list

hanzi_list_pinyin.append(single_str_py)

hanzi_list_pinyin_alias_dict[single_str_py]=single_str

hanzi_list_pinyin.sort()

sorted_hanzi_list=[]

for single_str_py in hanzi_list_pinyin:

sorted_hanzi_list.append(hanzi_list_pinyin_alias_dict[single_str_py])

return sorted_hanzi_list

str=['床前', '明月', '光','疑是','地上霜','举头','望','明月','低头','思','故乡']

print(str)

str=sort_pinyin(str)

print(str)

['床前', '明月', '光', '疑是', '地上霜', '举头', '望', '明月', '低头', '思', '故乡']

['床前', '地上霜', '低头', '光', '故乡', '举头', '明月', '明月', '思', '望', '疑是']

使用pypinyin必须传入unicode字符串

例子1

#!/usr/bin/python

# -*- coding: UTF-8 -*-

from pypinyin import pinyin, lazy_pinyin

py_r = pinyin(u"学python,我在行")

print py_r

print("整理下")

for py in py_r:

for p in py:

print p,"",

#发现上面的"行"字是多音字，本应念"han"

print("\n启动多音字")

py_r = pinyin(u"学python,我在行", heteronym=True)

print py_r

for py in py_r:

for p in py:

print p,"",

(venv) allenwoo@~/renren$ python test.py

[[u'xu\xe9'], [u'python,'], [u'w\u01d2'], [u'z\xe0i'], [u'x\xedng']]

整理下

xué python, wǒ zài xíng

启动多音字

[[u'xu\xe9'], [u'python,'], [u'w\u01d2'], [u'z\xe0i'], [u'x\xedng', u'h\xe1ng', u'x\xecng', u'h\xe0ng', u'h\xe9ng']]

xué python, wǒ zài xíng háng xìng hàng héng

例子2：

#!/usr/bin/python

# -*- coding: UTF-8 -*-

from pypinyin import pinyin, lazy_pinyin

# 不需要声调

py_r = lazy_pinyin(u"没有了诗和远方")

print py_r

# 特殊字符

# 默认

py_r = lazy_pinyin(u"满天都是小☆☆")

print py_r

# 不理睬，忽略

py_r = lazy_pinyin(u"满天都是小☆☆", errors=u'ignore')

print py_r

# 替换

py_r = lazy_pinyin(u"满天都是小☆☆", errors=u'replace')

# 也可以使用回调函数处理

py_r = lazy_pinyin(u"满天都是小☆☆", errors=lambda x: 'star')

print py_r

(venv) allenwoo@~/renren$ python test.py

[u'mei', u'you', u'le', u'shi', u'he', u'yuan', u'fang']

[u'man', u'tian', u'dou', u'shi', u'xiao', u'\u2606\u2606']

[u'man', u'tian', u'dou', u'shi', u'xiao']

[u'man', u'tian', u'dou', u'shi', u'xiao', 'star']

在第1个例子中，我们发现这个模块会简单分词，将"python"分为一个词

而且其他的中文词语并没有按词分开后再转拼音

自定义库：####

** 使用load_phrases_dict,自定义拼音库**

#!/usr/bin/python

# -*- coding: UTF-8 -*-

from pypinyin import lazy_pinyin, load_phrases_dict, TONE2

print lazy_pinyin(u"诗和远方", style=TONE2)

load_phrases_dict({u'远方':[['ju4'], ['keng1']]})

print lazy_pinyin(u"诗和远方", style=TONE2)

(venv) allenwoo@~/renren$ python test.py

[u'shi1', u'he2', u'yua3n', u'fa1ng']

[u'shi1', u'he2', 'ju4', 'keng1']
