.. _initials_problem:
``INITIALS`` 声母风格下,以 ``y``, ``w``, ``yu`` 开头的汉字返回空字符串
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
比如:
.. code:: python
pinyin('火影忍者', style=Style.INITIALS)
[['h'], [''], ['r'], ['zh']]
因为 ``y``, ``w``, ``yu`` 都不是声母。参考:
`hotoo/pinyin#57 <https://github.com/hotoo/pinyin/issues/57>`__,
`#22 <https://github.com/mozillazg/python-pinyin/pull/22>`__,
`#27 <https://github.com/mozillazg/python-pinyin/issues/27>`__,
`#44 <https://github.com/mozillazg/python-pinyin/issues/44>`__
声母风格INITIALS“雨”、“我”、“圆”等汉字返回空字符串因为根据
`《汉语拼音方案》 <http://www.moe.edu.cn/s78/A19/yxs_left/moe_810/s230/195802/t19580201_186000.html>`__
ywü (yu) 都不是声母,在某些特定韵母无声母时,才加上 y 或 w而 ü 也有其特定规则。
如果你觉得这个给你带来了麻烦,那么也请小心一些无声母的汉字(如“啊”、“饿”、“按”、“昂”等)。
这时候你也许需要的是首字母风格FIRST_LETTER。 —— @hotoo
如果觉得这个行为不是你想要的,就是想把 y 当成声母的话,可以指定 ``strict=False`` 这个可能会符合你的预期。详见 `strict 参数的影响`_
