i believe what you re looking for is the str encode  string-escape   function   For example  if you have a variable that you want to  raw string    a     x89  a encode  unicode escape      x89    Note  Use string-escape for python 2 x and older versions  I was searching for a similar solution and found the solution via  casting raw strings python

Since strings in Python are immutable  you cannot  make it  anything different  You can however  create a new raw string from s  like this   raw s   r     format s

For Python 3  the way to do this that doesn t add double backslashes and simply preserves  n   t  etc  is   a    hello nbobby nsally n  a encode  unicode-escape   decode   replace               print a    Which gives a value that can be written as CSV   hello nbobby nsally n   There doesn t seem to be a solution for other special characters  however  that may get a single   before them  It s a bummer  Solving that would be complex   For example  to serialize a pandas Series containing a list of strings with special characters in to a textfile in the format BERT expects with a CR between each sentence and a blank line between each document   with open  sentences csv    w   as f       current idx   0     for idx  doc in sentences items              Insert a newline to separate documents         if idx    current idx              f write   n             Write each sentence exactly as it appared to one line each         for sentence in doc              f write sentence encode  unicode-escape   decode   replace                   n     This outputs  for the Github CodeSearchNet docstrings for all languages tokenized into sentences    Makes sure the fast-path emits in order   param value the value to emit or queue up n param delayError if true  errors are delayed until the source has terminated n param disposable the resource to dispose if the drain terminates  Mirrors the one ObservableSource in an Iterable of several ObservableSources that first either emits an item or sends na termination notification  Scheduler  n  code amb  does not operate by default on a particular   link Scheduler    param  the common element type n param sources nan Iterable of ObservableSource sources competing to react first  A subscription to each source will noccur in the same order as in the Iterable   return an Observable that emits the same sequence as whichever of the source ObservableSources first nemitted an item or sent a termination notification n see ReactiveX operators documentation  Amb

raw strings apply only to string literals   they exist so that you can more conveniently express strings that would be modified by escape sequence processing   This is most especially useful when writing out regular expressions  or other forms of code in string literals   if you want a unicode string without escape processing  just prefix it with ur  like ur somestring

Just simply use the encode function  my var    hello  my var bytes   my var encode   print my var bytes   And then to convert it back to a regular string do this my var bytes    hello  my var   my var bytes decode   print my var    --EDIT-- The following does not make the string raw but instead encodes it to bytes and decodes it

Raw strings are not a different kind of string  They are a different way of describing a string in your source code  Once the string is created  it is what it is
