This is why raw strings exist.

>>> mystring1 = '\\"c:\\\\program files\\\\dimbo\\\\bongo.exe\\\\"
\\"c:\\\\program files\\\\dumbo\\\\my file.dat\\"'
>>> print mystring1
\"c:\\program files\\dimbo\\bongo.exe\\" \"c:\\program files\\dumbo\\my
file.dat\"
>>> mystring2 = r'\"c:\\program files\\dimbo\\bongo.exe\" \"c:\\program
files\\dumbo\\my file.dat\"'
>>> # note!     ^ the 'r' here!
>>> print mystring2
\"c:\\program files\\dimbo\\bongo.exe\" \"c:\\program files\\dumbo\\my
file.dat\"

Note that you've got an extra backslash in your version -- you want a
single escaped double quote after 'bongo.exe', not an escaped backslash
followed by an unescaped double quote.  Raw strings will save you much
pain.
