Hi Philip,
Your answer touches exaclty one point, which I was slightly afraid of:
- The list is not exhaustive
- python versions might have implemented different codecs.
This is why I wondered whether there's any way of querying python
for a
list of codecs it supports.
Try this:
Python 2.5.1 (r251:54863, Nov 17 2007, 21:19:53)
[GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import encodings.aliases
>>>
>>> encodings.aliases.aliases
"aliases" in the encodings.aliases module is a dict mapping alias
names (the dict keys) to encodings (the dict values). Thus, this will
give you the list of supported encodings:
>>> set(encodings.aliases.aliases.values())
The encodings module isn't in the documentation (?!?); I found it when
looking through the Python source code. For that reason I can't say
more about how it works. You may want to experiment to see if
encodings added via codecs.register() show up in the
encodings.aliases.aliases dict.
Have fun
Philip

Hi,
I was googling quite some time before finding the answer to my
question:
'what are the names for the encodings supported by python?'
I found the answer at http://python.active-venture.com/lib/node127.html
Now my question:
Can I find the same info in the standard python doc or query
python with
a certain command to print out all existing codings?
Look under the heading "Standard Encodings":
http://docs.python.org/library/codecs.html
Note that both the page you found (which appears to be a copy of the
Python documentation) and the reference I provide say, "Neither the
list
of aliases nor the list of languages is meant to be exhaustive".
I guess one reason for this is that different Python implementations
could choose to offer codecs for additional encodings.
