converting backslash codes

[Skaperen]

warning: very old thread

You mean marking the string as 'raw' by putting "r" in front of it?

>>> x = '\\n'
>>> y = r'\n'
>>> x == y
True

no.

i mean converting the kinds of backslash codes you might see expressed in source code, from being in actual strings to the binary result.

if i have code that reads input into a string and i type in a backslash and an 'r' i will have 2 characters, a backslash and an 'r'. source code to get exactly the same thing would be '\r'. but source code is merely explaining this; not how it is actually gotten. wherever those 2 characters come from, i want to apply the same effect as you see in source code:

    foo = '\r'

in the above case the variable named foo will end up with just 1 character. what i want (and have coded) is a function to do that.

my struggle has been explaining what i am doing. the "raw" concept is not what i am doing, although a reference to it might explain it to you. i'm thinking of it as an encoding.

perhaps this code would explain better what i have and what i want that can do the conversion

   abc = chr(92)
   xyz = chr(114)
   woot = convert(abc+xyz)
   print(ord(woot))

this would print out 13. what i want is that convert() function in a form that supports all such control codes.
