RE: Python 3.12 cannot import local python files as modules - sunflowerdog - Jul-26-2024

Quote:I don't understand it either. It may be a Windows-specific issue but I never use the Windows OS.

It is not very satisfactory but you could add the following lines in your sitecustomize or your usercustomize module to force the inclusion of the main script's directory in sys.path

from pathlib import Path
import sys

if sys.argv:
    sys.path.insert(0, str(Path(sys.argv[0]).resolve().parent))

Most likely I will just move everything to a Linux OS instead, seems like setting these sort of things up on Windows is unnecessarily broken and complicated.

To take a little about this 3 ways.
1.
Environment Variables Path can add folders here permanently to path,
see example under both version find same folders(use PYTHONPATH or just add folders to Path).

2.
Look at this post where use site module to add permanently to path.

3.
Virtual environment.
G:\div_code
λ python -m venv project_env

G:\div_code
λ cd project_env\

G:\div_code\project_env
λ G:\div_code\project_env\Scripts\activate.bat

G:\div_code\project_env
(project_env) λ
Now i can just copy folder/files from Project used before,then no path problems as Virtual environment add folder to sys.path automatic,.
G:\div_code\project_env
(project_env) λ python

>>> from project_env import bar, main

The issue with all of these approaches is that they require extra setup. Which is not the end of the world, but it's unnecessarily complex & kind of defeats some of the purpose of using a simple language like Python. I would much rather just use an installation of Python that works as intended. Ultimately, like I said previously, I'm probably just going to avoid using Windows and hope 3.12 on Linux does not have these issues.

I just tried in Linux with a Python 3.12.4 installed with pyenv and I don't have this problem.

By the way, the documentation taught me there is a pyenv-win program to get pyenv functionality in Windows OS. You could perhaps try with a version of Python 3.12 installed by pyenv-win to see if it has the same problem as your install of Python 3.12.

This problem of not understanding how sys.path work can arise on all OS Windows,Linux,Mac.
This problem has been asked here or other places many times for all OS.
From Python Doc The initialization of the sys.path module search path

If want to add some folders permanently it only takes a minute,using PYTHONPATH.
[Image: v9I7ZQ.png]
Other ways eg poetry it will make a package automatic with pyproject.toml and test folder.
This way will be easier if eg one day want to add package to PyPi,then just poetry publish.
Can just ad poetry later if have make a package and it's more serious project like want it on PyPi.
G:\
λ poetry new my_package
Created package my_package in my_package

G:\
λ cd my_package\

G:\my_package
λ ls
my_package/  pyproject.toml  README.md  tests/

G:\my_package\my_package
λ ls
__init__.py  __pycache__/  foo/  main.py
Use it two way.
G:\my_package
λ poetry run python

>>> from my_package import bar, main

>>> exit()
Or poetry will create a virtual environment automatic with poetry shell.

That is @sunflowerdog 's issue. This entry is not present in his module search path in Python 3.12. This is an abnormal situation. It cannot be corrected by adding permanently a folder in sys.path.

Maybe,but i would like sunflowerdog to make folder eg C:\code_1 with one file:
# hello.py
import sys

print('Test run a Python file')
print(sys.path)
print('-' * 25)
print(sys.executable)
Then from cmd do this here from start no edit.
Output:

So the problem now for sunflowerdog should be that it don't find C:\\code_1 folder as it dos for me here?

By any chance do you have Python-related environment variables set? Print them with

>>> print({k: v for k, v in os.environ.items() if 'PY' in k})

This to see if it same error is here,virtual environment is like new light Python version.

I guess not. When I first installed Python I did manually add Python's default script folders into my PATH because it wasn't recognizing pip at first, though I think that's moreso another symptom of the issue than the cause of it.
