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.
Definitely no issue of this kata!
Do not create an issue, if you are not sure, that the problem is in the kata!
As you can see, 53 people did this kata in python without any problems.
I think a reason for your problem could be, that you are changing the parameter-array. You should create a copy of the array and then change this copy.
I hope that helps. :-)
