Making a string raw

There is no such thing as a raw string! A string is a string is a
string (except for unicode strings) and it might, or might not,
contain back-slashes or non-ascii characters.
The 'raw' part has to do with string literals, which is how create
strings in a python program. Other ways of creating strings, such as
a Tkinter textbox, may or may not have an easy way to create string
values with various special characters. (If memory serves, a '\n' in
a tkinter textbox produces a two character string -- backslash
followed by "n".)
spam = r'hello'
eggs = 'hello'
produce exactly the same string value. Neither is raw or un-raw, and
both are Python strings with five characters.
The same hold true for the following two ways of creating strings:
spam = r'C:\abc'
eggs = 'C:\\abc'
Again the two strings have the same value, neither is raw or not raw,
and both have a backslash
If what you want is to take a string which has various backslash
sequences such as "\n" and convert such sequences into newlines, then
both of which specify replacing the two character string backslash-"n"
with a one character newline.
Hope that's all clear,
