Translating escaped characters

[Henrik S. Hansen]

How do you best go about translating characters like '\\n' to '\n'?
This is for a configuration file parser, where the "backslash
convention" is supported.

The naive approach -- re.sub('\\\\(.)', '\\\1', s) -- doesn't work, of
course. The best I've come up with so far is a special case for every
character to be translated. There must be an easier way?

Is this what you're looking for?
'\\n'

There's some info about it here:

http://docs.python.org/lib/node127.html

and searching Google Groups shows up a few things too:
