Translate escaped characters in a string

[-]

Hi

I have an application that reads the arguments sent to the script. If
an user enters a text like "Line 1\nLine2" (\n is slash+n, and not
LF), I would like to use \n and other supported escape sequences when
I write the text to a file.

Is there a way to do this, other than writing my own parser?

No, "\n" is backslash + n. Slash + n would be "/n".

Once you know the proper name for the character you're talking about,
you can find modules like this one:

which may be helpful.

I know there's an easier way to do it, but the below works...[color=blue][color=green][color=darkred]
>>> import encodings
>>> print encodings.codec s.escape_decode ('hello\\nworld ')[0][/color][/color][/color]
hello
world[color=blue][color=green][color=darkred]
>>>[/color][/color][/color]

If the stings are escaped normally, the above will produce what you want.
