[Tutor] How to write protect attributes or names

[Gregor Lingl]

Hi all,

is it possible to "write-protect" a definitive selection of attributes
(a) of a class
(b) of an object
(c) or a definitve selection of names of a module?
e.g. all the callable ones.
If so, how has it to be done?

Thanks in advance,
Gregor
