If you're getting the string from the command line, a \n will be
treated as backslash '\' followed by letter 'n', so it's equivalent to
the string literal "\\n".
In Python 2, you can unescape a string using its .decode method:
 >>> "My \\nquestion..."
'My \\nquestion...'
 >>> "My \\nquestion...".decode("string_escape")
'My \nquestion...'
