Some partial suggestions:
- Why do you use __? Use them only when necessary. My suggestion is to
use:
self._stack = []
- What's the purpose of stack = self.__stack ? It it does nothing
there.
- stack.append(current) can't find the stack name, because it's not
present in this scope, it's present into the __init__ only. My
suggestion is to use the instance attribute name.
You can probably fix that problem now.
