[Bug 1794229] Re: python packages should not ship colliding /usr/lib/python3/dist-packages/.pytest_cache

[Trent Lloyd]

It appears these packages are in main but mainly pulled in (at least on
my system) by 'devscripts'. This affects cosmic.

  python packages should not ship colliding /usr/lib/python3/dist-

Bug description:
  Python packages should not ship /usr/lib/python3/dist-
  packages/.pytest_cache

  Recently, two packages python3-alembic and python3-astroid both
  shipped these files which collided on package install

  dh-python has been improved upstream to stream all hidden "dot"
  directories in Debian #907871

  This change should be imported and both alembic and astroid should be
  rebuilt (plus any other packages shipping this file)
