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.
While doing this exercise on Python have an error: when my code compiles on codewars I have a result that is different from the result that I have with the same code in IDE(I have problems with sample tests). In IDE I have correct results with two sample tests, but on codewars I dont. Because of that I cant attempt the task. I use PyCharm btw.
