This is not necessary...

... since the default import path includes /usr/lib:

$ unset PYTHONPATH
$ python3 -c 'import sys ; print("\n".join(sys.path))'

/usr/lib/python38.zip
/usr/lib/python3.8
/usr/lib/python3.8/lib-dynload
/usr/local/lib/python3.8/dist-packages
/usr/lib/python3/dist-packages
/usr/lib/python3.8/dist-packages

Update PYTHONPATH after install

[Francis Murtagh]

Hi,

My understanding of Debian policy means python3 modules should be installed in 
/usr/lib/python3/dist-packages/

Once the package installs there how is the PYTHONPATH meant to be updated so 
that user can import the module into the python3 interpreter?

As the PYTHONPATH would normally look in /usr/local/ rather than /usr/lib/

Thanks,
Francis.
