List of Python Kata to Update - codewars/content-issues GitHub Wiki
- 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.
Python 3.8
This section lists kata that failed to update to Python 3.10 or 3.11 automatically.
Python 3.10
This section lists kata that failed to update to Python 3.11 from 3.10 automatically or was created with Python 3.10 after the attempt.

Test Framework
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.
