you must escape again your backslashes (\) (duplicating them)
because the 2 interpretation steps, from expression engine
and then from python interpreter, something like:

os.startfile("[% replace("DOC_Path", '\\', '\\\\') %]")

or just replace them with a slashes (/) since the python interpreter
replace slashes on path with backshashes on WinOS:

os.startfile("[% replace("DOC_Path", '\\', '/') %]")

I'd suggest the second approach because you're sure you don't
get any problems if the string is further interpreted and in
addition it should works on all the OSs.

Regards.
