os.path.splitext(fname) splits a filename into prefix and extension
parts:

    >>> os.path.splitext("hello")
    ('hello', '')
    >>> os.path.splitext("hello.doc")
    ('hello', '.doc')
    >>> os.path.splitext("hello.DOC")
    ('hello', '.DOC')
    >>> os.path.splitext("hello.foo")
    ('hello', '.foo')

in other words, "if not os.path.splitext(fname)[1]" might be what
you want.  or more readable:

    for fname in files:
        name, ext = os.path.splitext(fname)
        if ext:
            continue
        # ... figure out the new name and rename it ...
