Thanks for the hint,good kata

It stopped halfway probably because there are around 400+ tests.

I wanted to create a kata and loved the insert example helped me understand things better, my language is python.
I would like to see a kata in its raw form like i want to see example test cases too, the random ones.
Or a link to a site where i can learn this or videos anything is appreciated thanks

Thank you so much i now remember learning this long ago,thanks for refreshing my memory

I don't know where to post this question and it's quite silly but why is it that sometimes when the answer matches
exactly yet the test cases doesn't accept it because i used print() instead i use return then and it works anyone could help me understand why?

i switched to rank 6 kyu when i reached 130 honor points now i'm at 169 how much more to 5 kyu? even an estimate is fine
