Here's your first problem: the name "a" is not mapped to the same string you
think it is.  Python interprets the backslashes in a quoted string as escape
sequences, unless you specify a raw string by putting an "r" before the
first quotation mark.  Specifically, it interprets the sequence \1 as the
character with an ASCII value of 1.  So what you've done is:

>>> a = 'R0\1.2646\1.2649\D'
>>> print a

(The preceding line contains non-ASCII characters that may display oddly...)

I think what you really want is:

>>> a = r'R0\1.2646\1.2649\D'
>>> print a

Once you have stored your string properly, what's wrong with this?

>>> print a.split("\\")
['R0', '1.2646', '1.2649', 'D']

I don't actually read my hotmail account, but you can replace hotmail with
excite if you really want to reach me.
