An import that fails when the import statement looks perfectly fine is
often an indication that there is an error in the module to be imported.
It could be a simple indentation error, or something more serious. What
is the error message?

Import statements import packages, not directories.  The __init__.py
statement is processed when you import the package, and the modules are
processed when you import them from the package.  Although most
__init__.py files are empty, some code does some really serious work in
them  I like to use them to store the absolute directory path, which I
can use withr elative paths to compute where to put or find files - like
this (in the __init__.py ) -

import os.path
BASEPATH=3Dos.path.dirname(__file__)

Then you can import BASEPATH from the package.
