An alternative approach to this is via the use of scripts/_init_path.py

Usage: https://github.com/internetarchive/openlibrary/search?q=_init_path

The nice thing about using scripts/_init_path.py is that linters like flake8 and isort accept it.

Thanks @cclauss! That worked for me when I tested locally.

The python test seems to fail when I use _init_path @jimchamp

[jimchamp]

I'm going to defer to @cclauss and @cdrini for advice about fixing the failing test.

Do either of you know how to resolve the following?

ImportError while importing test module '/home/runner/work/openlibrary/openlibrary/scripts/tests/test_copydocs.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
/opt/hostedtoolcache/Python/3.9.13/x64/lib/python3.9/importlib/__init__.py:127: in import_module

@Suhas-13 can we see if copydocs works with the new revised instructions which include setting the PYTHONPATH? It's possible we can avoid having to add this change, which would be great! (Apologies if we sent you down a rabbit hole)

@cdrini maybe it's possible for us to add PYTHONPATH=. to our docker-compose setup (at least for dev)

I was able to import records using the updated copydocs instructions. I'm going to go ahead and close this PR and the linked issue. @Suhas-13, thanks for creating this PR! Even though it didn't get merged, your efforts have helped us troubleshoot and solve the issue.
