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.

THank you! But what do you call this sort of operation? - "%.2X%.2X%.2X" % [arr]- I'm looking for a key term to google so I can learn more about how to use this tool, and how it works. Is it shorthand for something else?
I feel like there is a fundemental principle or functionality at work here that I'm not familiar with, can someone point me in the right direction? What do i need to learn or read about to understand how to solve this? I see that there is a test generating a random number, and it seems that there should be a way for me to control the output of the test so I'm not just looping or guessing, right? Any direction is appreciated, thanks!
