If you don't have an __init__.py create one and add this line

from util.util import my_function

then you can easily import the module in your scripts the __init__.py tells python that it should treat that folder as a python package, it can also be used to import/load modules too.

in most cases the __init__.py is empty.

Quoting the docs:

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later.
