My own 'rule of thumb' in accessing from outside to the attributes
of a Python class  is "read attributes directly, but change them only via
methods". In other words, I treat all attributes in a class as 'readonly'.
This allow me to cut off amletic questions like "shall this be public of
private?", only to change it later on. The rule is so effective that I
tend to use it also in languages that allow public/protected/private
distinctions, like C++ and Java.
