In python 2 I can create a module like this:
parent
->module
->__init__.py (init calls \'from file import ClassName\')
file.py
->class Cla
Try import it this way:
from .file import ClassName
See here more info on "Guido's decision" on imports in python 3 and complete example on how to import in python 3.
In python 3 all imports are absolute unless a relative path is given to perform the import from. You will either need to use an absolute or relative import.
Absolute import:
from parent.file import ClassName
Relative import:
from . file import ClassName
# look for the module file in same directory as the current module
