All reports of package-contains-python-dot-directory for the archive. The extended description of this tag is:
The package contains a file that looks like cruft from the Python build process such as "pytest" cached output or similar.
As such files are unlikely to be of utility to end-users they should not be shipped in the final binary package. They could also conflict with files from other packages and/or affect the reproducibility of your package.
Please rebuild using a newer version of pybuild/dh-python which will automatically remove many of these files.
This tag has not been emitted in any package tested by Lintian.
