的Python：有沒有辦法從編解碼器名稱

Question

獲得語言的名字，我想是可以這樣做的以下功能：

def get_lang(enc): 
    ... 

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

這可能嗎？

更新： 我的意思是，就像這本手冊中：http://docs.python.org/library/codecs.html#standard-encodings

Answer 1

沒有，沒有包含該信息的任何廣泛可用的模塊。

我建議解析文檔（從http://hg.python.org/cpython/file/tip/Doc/library/codecs.rst#l926或http://docs.python.org/_sources/library/codecs.txt）構建查找字典，就像@fraxel似乎已經完成的那樣。由於編解碼器很少被添加到Python中（並且越來越多地被Unicode替換），這種方法應該是合理的未來發展。

是的，你可以使用這本字典：
