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.
OP solved it, closing
mind elaborate?
Re-read the Kata description properly:
The delimiter between the data and the filename is a single underscore. If there are multiple underscores, then naturally the latter underscores are not part of the delimiter.

This is not a way to report an issue, do it properly next time.
Please which language? I have to suppose from your profile it is Python...

I tried your solution. You fail but not where you said in your post.
You get a STDERR.
I'd suggest looking into regular expressions, i.e. using the 're' module in python. There's a convenient 'sub' method.
