In Python, the backslash is a character escape character.  In order
to include a backslash in a string, use a double backslash.  Here
is some example code::

    In [1]: s1 = 'abcd\\efg\\'
    In [2]: s1
    Out[2]: 'abcd\\efg\\'
    In [3]: len(s1)
    Out[3]: 9
    In [4]: s1.replace('\\', '')
    Out[4]: 'abcdefg'

Notice the length of the string (before removing the backslashes). 
Each apparently double backslash actually has a length of 1.
