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.
Okay so, I wrote a solution and it passed all the test cases, but I get an error in the end saying:
Traceback:
in
in unique_in_order
TypeError: expected string or buffer
I'm not sure how to correct it since the test results indicate Time: 59ms Passed: 8 Failed: 0
Has anyone encountered this before?
