A raw string doesn't translate escape sequences and such. Raw strings are
preceeded by an 'r'. Example:

>>> print 'Hello\n'

>>> print r'Hello\n'
>>> 'Hello\n'
>>> r'Hello\n'

In a raw string you can put special characters and likewise how you want
without them getting their special meaning, they are just characters. Or you
can see it so that Python automatically escapes the special characters so they
lose their special meaning.
