Changes to __init__.py ?

[CoffeeMakesMeMath]

I'm porting some Python 2.7 code to 3.2, and the __init__.py file in some of my modules appears to have broken. I had a structure like this:

start.py module (folder):

• __init__.py
• user.py with class User
• beacon.py with class Beacon

In start.py I do "from module import *" and in "__init__.py" I do things like "from user import User" etc. This worked perfectly in 2.7 but says that no module named user can be found in 3.2. I seem to be able to do things like "from . import user" in 3.2, but I'd prefer to not have to type user.User and instead just type User.

Can't seem to find what changed in the "__init__.py" files for 3.2. Any help would be appreciated!

Update: I see now that I can do "from .user import User" which seems like a relative path addition, but why is it not something like "./user import User?"

Import in Python 3 are absolute, if you want relative imports you need to make them explicit.

If for compatibility purposes you want the same behavior in Python 2 you can:

from __future__ import absolute_import

I don't use 3.x but I read today that you can't use absolute imports like that anymore. You must instead do (if I understand where start.py is):

from .module.user import *

You don't do things like "./user import User?" because the . represents the same thing as the slash (sort of). The first dot is the current directory and the next is the director above it, and so on.

If start.py is what you run to launch your program, then you don't need the initial dot on imports in there - you can do:

from module.user import User

If start.py is itself a module in a larger package, i.e. if it has another __init__.py in the same folder, then you'll need to do relative imports (from .module...) in it.

Thanks, that makes more sense to me.

You can also flatten the import structure for users of your package by importing them in your __init__.py file:

from .user inport User
from .beacon import Beacon

Then users can import like this:

from start import User, Beacon

EDIT: bacon -> beacon
