your code checks all members, even if the first one's false.  that's not 
very elegant.  here's a better way to do it:

     def all(S):
         for x in S:
             if not x:
                return False
         return True

     print all(logfiles)

if you upgrade to 2.5, you can get rid of the function definition; "all" 
  is a built-in in 2.5.
