The OP used os.path.isfile().
Depending on what you want to achieve, each of three methods might be
appropriate. Calling os.stat() just tells you whether the thing exists
(but of course its return value gives you a lot of extra information).
os.path.isfile() tells you whether it's a file (and it is shorter, too).
open() tells you whether the file is readable.
