Why not just

dirpath = r'c:\test'
if not os.path.isdir(dirpath):
    dirpath = '/home/user/test'  # ~/test ?? or is there an account named "user"?
    # or maybe '/home/%s/test'%os.popen('whoami').read().strip()  #untested

IWT it's fairly safe to assume the windows path is not going to exist on unix
unless something strange is going on. This way you don't have to worry about
different flavors of unix and windows.
