File importing on python project

I want to have following project directory structure in python:

project

    generic.py

    subdir1

        file1.py

    subdir2

        file2.py

    subdir3

        file3.py

within file1.py I want to import generic.py from a root dir of project.

import generic

Unfortunatelly I got error when a try to execute "file1.py"

root:~/project/sidir1# python file1.py

Traceback (most recent call last):

  File "file1.py", line 7, in <module>

    import generic

ImportError: No module named generic

I want to execute individual file*.py and have generic.py included.

How to correctly include it under such a drirectory structure?

You can make your python project a package by making __init__.py in the root directory.

You can then use relative imports, ex: from .. import generic

It's cause of Python path, when you use import, python will try to find in every directory in sys.path if module with name given exist, if he don't found, he raise.

For fix your problem, just add parent directory to your python path

import sys

sys.path.append("..")

I would encourage you to instead wrap generic.py within a package along with the other submodules. Importing from root is usually a good recipe to later needing to debug imports that no longer work the way they should. Relative imports within a package can also become problematic.

Just build a structure like this:

project

    my_package

        generic.py

        __init__.py

        subdir1

            file1.py

            __init__.py

        subdir2

            file2.py

            __init__.py

        subdir3

            file3.py

            __init__.py

And now in file*.py do: from my_package import generic

Now on the project level put a main.py or similar script where you use the functions that are available in my_package.

Just build a structure like this:

project

    my_package

        generic.py

        __init__.py

        subdir1

            file1.py

            __init__.py

        subdir2

            file2.py

            __init__.py

        subdir3

            file3.py

            __init__.py

And now in file*.py do: from my_package import generic

Now on the project level put a main.py or similar script where you use the functions that are available in my_package.
