Something like this might work:
import os
import encodings
names = encodings._cache.keys()
for file in os.listdir(os.path.dirname(encodings.__file__)):
name, ext = os.path.splitext(file)
if ext == ".py" and name not in names:
try:
encodings.search_function(name)
except SystemError:
pass
else:
names.append(name)
print "codecs:", names
print "aliases:", encodings.aliases.aliases.keys()
if you wish to speed it up, you can skip the call to search_function,
and just filter out "__init__" and "aliases".
Hope this helps!
