# 🐞 bug report

### Affected Rule

rules_python

### Is this a regression?

No

### Description

Running `bazel coverage` does not produce coverage reports for all versions of Python. The coverage.dat files are empty when using Python version 3.10.15 and 3.10.16. Other versions of Python 3.10 do seem to produce valid coverage reports.

I did not test Python 3.11 or 3.12.

## 🔬 Minimal Reproduction

I added tests on a fork of main: [python-3-10-16-coverage](https://github.com/keesvanhespen/rules_python/tree/python-3-10-16-coverage).

Running

`bazel coverage --action_env=COVERAGE_GCOV_OPTIONS=-b --combined_report=lcov --strategy=CoverageReport=local -- //test_code/...
`

from the `tests/coverage` directory returns a filled coverage.dat file in bazel-out for Python 3.10.14, but it is empty for 3.10.16.

Línea de trabajo

Start in tests/coverage and compare the reported bazel coverage command and coverage.dat output for Python 3.10.14 versus 3.10.15 and 3.10.16, using the linked python-3-10-16-coverage branch as the reproduction. Done means coverage.dat is populated for the affected Python versions and the coverage tests pass.
