- Python 3.8 List of kata stuck in Python 3.8. Should be prioritized so we can get rid of the older version. Note that updating to decorator syntax is not required.
- Python 3.10 List of kata stuck in Python 3.10.
- Update to decorator syntax List of kata not using the new decorator syntax.
NOTE: Simply remove the kata from the list after updating.
This section lists kata that failed to update to Python 3.10 or 3.11 automatically.

- Find Ends of Each Paths
- One Line Task: Zero Or One

This section lists Python kata without @test.it in submission tests. This doesn't prevent Python 3.8 upgrade, but we'll be able to make the test framework behave less awkwardly if we can update all kata to the new syntax.
