Question

我想要一个可以执行以下操作的函数：

def get_lang(enc):
  ...

>>> get_lang('ascii')
'English'
>>> get_lang('big5')
'Traditional Chinese'
>>> get_lang('utf-8')
'All languages'

有可能吗？

更新：我的意思是，就像手册中的http://docs.python.org/library/codecs.html#standard-encodings

一样

Answer 2

不，没有任何广泛可用的模块包含该信息。

我建议解析文档（来自http://hg.python.org/cpython/file/tip/Doc/library/codecs.rst#l926或http://docs.python.org/_sources/library/codecs.txt）以构建查找字典，因为@fraxel似乎已经完成了。由于编解码器很少被添加到Python中（并且越来越多地被Unicode替换），这种方法应该是合理的未来证明。

Python：有没有办法从编解码器名称中获取语言名称
