dear ChrisA ,dynamic is python feature, it is to create descriptor in
run time ,
that is the meaning in the codes,and maybe it is a bug:
the attribute can be displayed in dir(man) after be deleted.

Look. Forget properties. Python is not Java or C++, and you almost
never need this kind of thing. Read up a tutorial on doing classes
Python's way, and you'll find that all this sort of thing just doesn't
matter. You've come here with a significant number of questions about
properties, and it looks as if you're trying to do everything through
them - which is utterly and completely useless, especially when you
use properties to be as dynamic as you're doing. Just don't do it.
