PYTEST.pyc files

[Orion Poplawski]

It appears that in at least some situations pytest will create 
-PYTEST.pyc files, and sometimes (always?) with weird permissions:

-rw-------. 1 root root 1614 Jul 13  2018 
/usr/lib64/python3.7/site-packages/cytoolz/__pycache__/utils_test.cpython-37-PYTEST.pyc

I've noticed the following packages have them:

pytest-4.4.1-1.fc31.src.rpm
python-astropy-healpix-0.4-1.fc31.src.rpm
python-cytoolz-0.9.0.1-3.fc30.src.rpm
python-healpy-1.12.9-1.fc31.src.rpm
python-pytest-repeat-0.8.0-1.fc31.src.rpm
python-pytest-rerunfailures-6.0-1.fc31.src.rpm
python-pytest-shutil-1.6.0-2.fc31.src.rpm
python-reproject-0.4-6.fc30.src.rpm
python3-pytest-asyncio-0.10.0-1.fc31.src.rpm
scipy-1.2.1-1.fc31.src.rpm

These can be prevented by setting PYTHONDONTWRITEBYTECODE=1 when run pytest.

Can anyone else shed more light on this?  Should we add this to the 
guidelines? (Possibly not since there do not appear to be many packages 
like this).  I suspect it comes in when has to set 
PYTHONPATH=%{buildroot}%{python3_sitearch} due to needing to load 
compiled modules.
