why does python os.path.isfile seem to ignore certain file types?
<p>simple script on a unix system (Mac) which seems to only return certain files True.  Can't figure out why:</p>

<pre><code>workdir = '/Volumes/place/sub place'

def myFunc(bla, dir, flist):
    for f in flist:
         print f, os.path.isfile(f)

os.path.walk(workdir,myFunc,None)
</code></pre>

<p>Returns:</p>

<pre><code>tests.py False
utils.py False
utils.pyc False
writeXmlForMpgInPath.py False
.DS_Store True
Playout False
Playout Masters False
Projects False
ProRes Masters False

Web Preview False
.AU009644-M.xml.swp False
