Hmm . . .  I'm still a bit confused . . .  The naming doc says that

from MyClass import MyClass

will only import the stuff that is part of the class scope (if I read it correctly).  But it appears to also read and 
use the 'import os' at the module level for the MyClass.py file.

The second question is why "import os" doesn't work at the interactive prompt; once I say that, isn't that a 'global' ??

Thanks!
