Attribute not added to module after importing

Question

I\'ve made the following lab:

vagrant@ubuntu-xenial:~/test$ tree
.
├── pack1
│   ├── __init__.py
│   ├── mod1.py
│   └── pack2
│       ├── __init__.py
│       ├─         


        

Answer 1

A module is added as an attribute of its package when its import finishes. (Note that this can interfere with circular relative imports.) Here, pack2 immediately imports mod2, so (regardless of further completed imports like that of mod3) it doesn’t appear in the pack1 dictionary during mod2’s execution.
