Pinyin2Hanzi实现拼音转汉子的功能，但是，拼音必须是规范的。否则会出现如下情形：
# 拼音转汉字
from Pinyin2Hanzi import DefaultDagParams
from Pinyin2Hanzi import dag
def pinyin_2_hanzi(pinyin_list):
dagParams = DefaultDagParams()
result = dag(dagParams, pinyin_list, path_num=3, log = True) # path_num代表候选集个数
for item in result:
score = item.score
res = item.path # 转换结果
print("score = {}, ressult = {}".format(score, res))
if __name__ == '__main__':
lst = ['xue', 'xiao']
# lst = ['xve', 'xiao']
pinyin_2_hanzi(lst)
返回结果为空。
解决办法
因此，我们需要对拼音进行修正。Pinyin2Hanzi模块提供了修正的算法模块：simplify_pinyin
# 拼音转汉字
from Pinyin2Hanzi import DefaultDagParams
from Pinyin2Hanzi import dag
def pinyin_2_hanzi(pinyin_list):
dagParams = DefaultDagParams()
result = dag(dagParams, pinyin_list, path_num=3, log = True) # path_num代表候选集个数
for item in result:
score = item.score
res = item.path # 转换结果
print("score = {}, ressult = {}".format(score, res))
if __name__ == '__main__':
lst = ['xue', 'xiao']
# 拼音转规范
from Pinyin2Hanzi import simplify_pinyin
lst_simplified = []
for item in lst:
lst_simplified.append(simplify_pinyin(item))
print("修正后的拼音为：", lst_simplified)
pinyin_2_hanzi(lst_simplified)
此时，返回结果为：
修正后的拼音为：['xve', 'xiao']
score = -1.0809033989236891, ressult = ['学校']
score = -4.1501850243170555, ressult = ['学', '小']
score = -4.280325124338203, ressult = ['学', '效']
