From: jwither on 7 Sep 2009 01:29 Given a string (read from a file) which contains raw escape sequences, (specifically, slash n), what is the best way to convert that to a parsed string, where the escape sequence has been replaced (specifically, by a NEWLINE token)? James Withers

As is "\r\n" and "\r". Choose your demon. mystring = mystring.replace("\n", demon) FYI. If you are reading from a file, you can iterate over the lines without having to worry about newlines: fi = open(path_to_file, 'r') for line in fi: process_line(line) ~Sean

There's probably a more general method covering all the escape sequences, but for just \n: your_string = your_string.replace("\\n", "\n") Cheers, Chris -- http://blog.rebertia.com

(the others are more likely to be errors than deliberate anyway) James Withers |
