is one place that talks about them in a little more detail. Actually,
there appears to be a lot of controversy about the implementation of the
'.DS_Store' mechanism in the Finder; I googled for it, and the first thing
that comes up is a program to remove '.DS_Store' files. *grin*

It shouldn't have to be ugly, if we add one level of indirection:
"""A specialized version of os.listdir() that ignores files that
start with a leading period."""
filelist = os.listdir(directory)
return [x for x in filelist
if not (x.startswith('.'))]
We can use 'mylistdir()' function instead of os.listdir(). By writing a
helper function, we can limit the scope of the change to, effectively, a
Hope this helps!
