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 might be using the wrong string method on the wrong string.
Hopefully I've said enough but not too much.
Before posting issues please look at the top of the page: 1007 people passed the Python kata so if there were errors several people would have seen them before you. Issues are for errors in the kata, not for problems in your code.
Changing ranks is expensive, not worth it, and not going to happen. Just enjoy the cheap points.
Moreover, consider ranks are shared among languages and can vary a lot depending on each one.
