Double leading underscore (__write) causes name-mangling in python, so
that derived class can't (directly) access properties of base class (and
vice versa, as was the problem here)
Missing call to super().__init__ in derived class, causing undefined
properties because the base class' constructor was never executed
Some encoding issues (str vs. int vs. bytes). Probably just a python3
thing tough.
