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.
Thanks for your post.
You could use nested function when possible.
Happy you found the reason :-)
OK. I see the line in the tests. But AFAIK range in 3.x takes 2 arguments as well as in 2.7 so I don't understand why you got this TypeError. I tried different solutions with the different proposed versions of Python (2.7.6, 3.4.3, 3.6.0) for this kata and had no problem. Which version did you use? As I can see CW proposes the 3.4.3.
Small note: no need to downvote my post. It doesn't make things easier.
454 guys passed the Python kata; I just tried several solutions and had no problem. So I think it is not an issue of the kata but maybe a problem in your code.
