List of Python Kata to Update

saudiGuy11 edited this page Dec 26, 2024 · 779 revisions
  • 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.
