Python: Improve test coverage in 5 places for production code

[niccokunzmann]

The production code is mostly covered by the tests. Sometimes, __repr__ or if conditions are not covered though. That would be nice!

To close the issue:

• [ ] cover 5 additional spots in the tests
• [ ] create a pull request with your changes and get it merged

What will help:

• Follow the documented development setup
• After running the tests, you will have a coverage report as an HTML file.
• Create a Pull Request and we will see the improvements.

We are working on this. Would you like me to send a PR to add --branch to the coverage run options in tox.ini?

You are welcome to create PRs with improvements or create issues to discuss those first.
