That's to be expected.  When not using a print statement, the raw 
evaluation prints the representation of the object.  In this 
case, the representation is 'b\nb'.  When you use the print 
statement, it actually prints the characters rather than their 
representations.  No need to mess with re.sub() to get the behavior:

   >>> s = 'a\nb'
   >>> s
   'a\nb'
   >>> print s
   a
   b
   >>> print repr(s)
   'a\nb'
