Just to further emphasise this point try printing your strings (using 
print())
and you will see the difference:

>>> test = r"a \n b \n c \n"  # using raw 'r'
>>> test2 = """
... a
... b
... c
... """
>>> test3 = "a \n b \n c \n"  # no raw 'r'
>>> print(test)
a \n b \n c \n
>>> print( test2)

a
b
c

>>> print(test3)
a
 b
 c

>>>
