[Tutor] import aliases ?

[spir]

Hello,

In the case of such a dir structure:

/pack
   __init__.py
   (modules)
   /pack1
      __init__.py
      modules

are the following imports synonyms:
1-   import pack.pack1
2-   from pack import pack1
?

If yes, is there a reason for this?

Also, there is something I find weird:

* Using idiom 1, pack1 is only known as the compound name "pack.pack1": I cannot eg "print pack1". Consistently, to import a module, I need "from pack.pack1 import mod".

* Using idiom 2, pack1 is known as "pack1" alone: I can "print pack1", which outputs "<module 'pack.pack1' from '/home/spir/prog/python/pack/pack1/__init__.pyc'>".
But for further imports, I still need to use the compound name "pack.pack1": "from pack1 import mod" raises "ImportError: No module named pack1", while python has just accepted to print pack1!
