(I'm surprised I haven't seen replies to this yet.)
One alternative would be to use mode w the first time and then mode a thereafter.
I believe it is simpler to simply delete the files at the beginning.  This can be
done by:

import os
# assumes that your known filenames are in fnamelist
for fname in fnamelist:
	os.remove(fname)
If the file names in the fname list refer to file in some other directory,
	os.remove( os.path.join(r'c:\some_other_dir', fname))

(Code was simply typed in and not tested.  it should be close to correct.)
