Python modules importing

Question

I have folder with such structure:

parent/
   ---__init__.py
   ---SomeClass.py
   ---Worker.py

First file (__init__.py) is empty.

Second file (SomeClass.py) content is following code:

class Test:
   pass

Third file (Worker.py):

import SomeClass
Test()

ImportError: No module named SomeClass

What I do wrong?

For me it fails in a different way - it fails to resolve Test() symbol. And that's fine - you need to either use the fully qualified name 'SomeClass.Test()', or import it into the module's name space: 'from SomeClass import Test' and left the second line as is. This doesn't answer your original question, however. How are you spawning this code? — Code Painters

Where are you running the program from, and how (e.g. import parent.Worker)? — Sam Magura

you mean python Worker.py from within 'parent'? Or importing it from the directory one-level up, as Sam Magura suggested? Give us more details :) — Code Painters

Try

from . import SomeClass

but remember you'll have to

SomeClass.Text()

instead of just Test()

Well I messed up, you can use it in 2.x too.

relative imports are Python 2.6 and later

Ah, yes I only checked 2.7. Using 3.x really makes hard dealing with 2.x issues. Well that was my reason to chose 3 =)
