Might I suggest you use encode and decode instead?
>>> 'first line\nsecond line'.encode('string-escape')
'first line\\nsecond line'
>>> _.decode('string-escape')
'first line\nsecond line'
>>> u'first line\nsecond line'.encode('unicode-escape')
'first line\\nsecond line'
>>> _.decode('unicode-escape')
u'first line\nsecond line'
