Simpler still is almost always to use forward slashes instead:

os.path.isfile('c:/bookmarks.html')
os.path.isfile('c:/wumpus.c')

The only time this doesn't really work is when you pass the path to the 
Windows "shell".  Or when you naively compare paths without using 
something like normpath() on them first...
