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'
是否可以？
更新：我的意思是，就像手册中这样：http: //docs.python.org/library/codecs.html#standard-encodings

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）来构造一个查找字典，就像@fraxel 似乎所做的那样。由于编解码器很少被添加到 Python 中（并且越来越多地被 Unicode 取代），这种方法应该是合理的面向未来的。
