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.
Hi Alexey - I don't know how you are currently counting your characters to reach 24 - are you only including the Latin letters in your code in this total, ignoring the punctuation etc? - but to me your answer appears as 54 characters in total.
The Python limit for this kata challenge is 52 so you need to reduce a bit more.
To be clear - if you take your solution (all of it, not just the part after the function definition) into your standard text editor and select it as a block, it should say 54 characters selected.
