汉字到拼音的转换

汉字到拼音的转换可以看看 pinyin.py git库。
在博客Python汉字转换成拼音中提出了英文兼容性问题，也提出了兼容方式，评论中也有改进。但是英文变成了一个一个的字母，和我们大众有点区别了，我也对原项目进行了一些更改，对英文词汇支持。

    def hanzi2pinyin(self, string=""):
        result = []
        if not isinstance(string, str):
            string = string.decode("utf-8")
        split_strings = string.split()
        for split_string in split_strings:
            spell = ''
            for char in split_string:
                key = '%04X' % ord(char)
                if ord(char) > 128 and spell != '':                 
                    result.append(spell)
                    spell = ''
                elif ord(char) <= 128 and ord(char) >=0:
                    spell += char
                elif ord(char) >= 13312:        #   (13312)10 = (3400)16 
                    temp = self.word_dict.get(key, char).split()[0][:-1].lower()
                    result.append(temp)
            if spell != '':                 
                result.append(spell)
        return result

输出为：

in: 钓鱼岛是中国的inherent territory
out: ['diao', 'yu', 'dao', 'shi', 'zhong', 'guo', 'de', 'inherent', 'territory']
out: diao-yu-dao-shi-zhong-guo-de-inherent-territory

由于我的环境是python3,有些细节做了写改变，整个文件如下：
