How to import python file located in same subdirectory in a pycharm project

Question

Recommended Way:

Make sure to set the working folder as Sources.

You can do it in Pycharm -> Preferences -> Project: XYZ -> Project Structure

Select your working folder and mark it as Sources. Then Pycharm recognize the working folder as a Source folder for the project and you will be able to simply add other files within that folder by using

import filename.py

or

from filename.py import mudule1

=================

Not recommended way:

In Pycharmyou can simply add . before the .py file which you are going to import it from the same folder. In your case it will be

from .util import my_functions

There is a good reference also for more information with example how to implement Package Relative Imports. I would highly recommend to check this page.

Package Relative Imports

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.

Right-click on the folder which you want to be marked as the source > Mark Directory as > Source root.

Note: May be a bit unrelated.

I was facing the same issue but I was unable to import a module in the same directory (rather than subdirectory as asked by OP) when running a jupyter notebook (here the directory didn't have __init__.py). Strangely, I had setup python path and interpreter location and everything. None of the other answers helped but changing the directory in python did.

import os
os.chdir(/path/to/your/directory/)

I'm using PyCharm 2017.3 on Ubuntu 16.04
