Protection levels in Python

[Kay Schluehr]

People often ask for making attributes "private" in the sense of
restricting access as in Java or C++. I've created a recipe for
attribute protection where all attributes are basically protected in
the C++ sense of being visible in the class and in subclasses and where
"public" attributes have to be declared explicitely:
