I keep getting the same problem - if inherit from any of these classes 
in BaseHTTPServer and try to use super(class, self) to initiate the 
higher class, I get the error "TypeError: must be type, not classobj" - 
in other words, these are old-style classes.
That means that in this call -
self.httpd = MyHTTPServer(('127.0.0.1', 8000), MyRequestHandler)

there doesn't seem to be a way to define a
  class MyHTTPServer(HTTPServer)
