[Python-Dev] Allowing import star with namespaces

[Brendan Moloney]

We all know that doing:

> from pkg import *

is bad because it obliterates the 'pkg' namespace. So why not allow something 
like:

> import pkg.*

This would still be helpful for interactive sessions while keeping namespaces 
around.

Sorry if this has been brought up before, my searching didn't find anything 
relevant in the archives.

Thanks,
Brendan

Sorry, I phrased that badly.  When I said "obliterates the 'pkg' namespace" I 
was referring to dumping the 'pkg' namespace into the current namespace 
(polluting it, as you would say).

Because that does not import all of the (public) modules and packages under 
'pkg'. For example scipy has has a subpackage 'linalg'.  If I just do 'import 
scipy' then I can not refer to 'scipy.linalg' until I do 'import scipy.linalg'.

Sorry, didn't realize that would be the more appropriate list. 


Thanks,
