That question makes no sense -- a string is a string is a string in 
Python.   The syntax you use to specify the string (for instance, raw or 
not, hex characters or not, or one or another quote choice) is 
irrelevant and completely forgotten once the string is internal.

No need to use replace, the \n is already stored as a newline, and the 
\t as a tab and so on.    Various methods of output may or may not 
convert those characters back into \n and \t and so on.  But that's a 
matter of output not internal storage.

So tell us what you're trying to accomplish -- and better also tell us 
Python2 or Python3?
