You have the right idea, although this would be a bit cleaner:

for root, dirs, files in os.walk( 'foo' ):
    for name in files:
        etc...

You might want to take a look at the documentation for os.walk. It explains
all this and has a couple of good code samples.

You mean if you run Python from the *parent* directory of foo, right?

'foo' is a relative path, not an absolute one, so it gets appended to the
current directory.
