using property and setter it seems I must use “__name” or “__volume”
(Python’s version of private variables). Is this true?
Certainly not. Python doesn't enforce any naming convention on you. You
can use any name you like. But you *should* use something like "__name"
or "__volume", simply because that will be more sensible than most other
names. But if you choose to use something else, Python won't stop you.
Note that use the doubleunderscore names is a special construct that
invokes name mangling. You might want to introduce them when teaching
about sub-classing. Pep 8 speaks to their use. See
