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 comments. I have updated the description. :)
I agree.
And the default value of the list is not
0but[0].And actually, it should be
[0.0]And instructions are quite painfully poor, when you try to do this kata without the statistic module: rounding the elements of the list before calculating the average can lead to an error, so you should not say "Round and format all values with one decimal place" but rather "Round and format all values with one decimal place AFTER all the calculations are done".
