Summary: import not pythonic in 2.1.1

Initial Comment:
Take a package 'aPackage', which contains a sub-package 'aSubPackage' that in turn contains a 
module 'aModule' that defines a class 'aClass'.

If I do:

import aPackage.aSubPackage
print aPackage.aSubPackage.aModule

I get:

Traceback (most recent call last):
  File "x.py", line xx, in ?
    print aPackage.aSubPackage.aModule
AttributeError: 'aPackage.aSubPackage' module has no attribute 'aModule'

A yet, if I do:

import aPackage.aSubPackage.aModule
print aPackage.aSubPackage.aModule

I get:
<module 'aPackage.aSubPackage.aModule' from 'some_path'>

...as expected, which is very confusing and doesn't feel 'right' :-S

Okay, if it's intended, that means there's a good reason for it...

...where can I look for enlightenment as to what that is?

cheers,

Chris

Better adjust your intuition. :-)

This is as intended. Attributes of packages that are
*modules* are only loaded when the corresponding module is
explicitly imported (by you, or by some other code, e.g. the
package's __init__.py).
