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 can also use a lambda expression like this :
minus = lambda x, y: x-yWell, kumites are free for all, so...
There are lots of issues with the kumite list page though. e.g it doesn't even have paging.
In your opinion is bad idea to tell someon how to add two numbers in simplest way if someone asking for answer? maybe all solutions is't great but are solutions too.
What the hell are all these kumites? Is this some kind of "bad practices shitpost"?
