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.
