Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
You can print the inputs to see which tests you are failing.
Random tests are actually bad in Python, you would fail more than one test.
Your function is returning strings, not booleans, not a kata issue. Read this: https://docs.codewars.com/training/troubleshooting/
