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.
Thank you.
I was really distracted with the error I got.
I need some help with this problem. Does it mean than my code is wrong or the test is bugged? What should I do?
File "tests.py", line 6, in
test.expect(greek_comparator('alpha', 'beta') < 0, "result should be negative")
TypeError: '<' not supported between instances of 'str' and 'int'
