filecmp.dircmp.report is a method in the filecmp.dircmp class. You have to
subclass from another class and you cannot subclass from a method. What you
probably want is define a subclass of filecmp.dircmp (like your own dircmp)
and define a method report(self) inside it. This means that you are
overriding the superclass's report( ) method. Inside your report( ) method,
you can still use the filecmp.dircmp.report method like this:
Hope this helps.
