Title
Body
I am trying to implement string unescaping with Python regex and backreferences, and it doesn't seem to want to work very well. I'm sure it's something I'm doing wrong but I can't figure out what... >>> import re >>> mystring = r"This is \n a test \r" >>> p = re.compile( "\\\\(\\S)" ) >>> p.sub( "\\1", mystring ) 'This is n a test r' >>> p.sub( "\\\\\\1", mystring ) 'This is \\n a test \\r' >>> p.sub( "\\\\1", mystring ) 'This is \\1 a test \\1' I'd like to replace \\[char] with \[char], but backreferences in Python don't appear to follow the same rules they do in every other implementation I've ever used. Could someone shed some light?
