I am asking about module privates, not class privates.
Suggested in here, a module private starts with one underscore, such a element is not copied along when using the from <module_name> import * form of the import command; it is however imported if using the import <moudule_name> syntax.
So the question is if I have to use import <moudule_name> syntax, how to avoid importing module private functions?
module_name._privatemembers. The_privatedefinitions will be executed regardless of whether you import them or not, so there's not any particular benefit to not importing them, just so long as you don't touch them.
