Because they're pointless. Java interfaces are a hack around the
complexities of multiple inheritence. Python does multiple
inheritence Just Fine (give or take the subtleties of super()) so
does not need them.
Interfaces used purely with the idea of type safety provide
precious little gain for the added clutter and inconvenience.
Compare them to Java's requirement for explicit declaration of
exceptions thrown in a method signature, if you will.
