lol I didin't know this method islnum exists

Same. Never before have I seen it used or even heard of it. Immediately down the rabbit hole!

Never have I looked at more library documentation than when looking at your solutions. Thanks for making me get out of my comfort zone!

That would be a big fat no. Please leave me alone in my shame. 😆

Did you read this in the description:

Content is in fact not necessary in the body of the function "evaporator", you can use it or not use it ...

Too easy

👍

elegant

(most tags are actually automatic, hence most aren't appropriate: the heuristic used is rather poor)

Thank you, I will definitely do that.

I suggest reading this
https://docs.python.org/3/reference/datamodel.html#special-method-names
And implement a linked list class, supporting iteration, indexing (get and set, possibly slicing), string conversion, concatenation, ==, < >

I imagine kata's using the class tag all sprinkled on some oop dust without it being very meaningful.

Thank you both very much. Though I have ranked up to 3 kyu I am very weak on Classes and am forcing myself through all Classes tagged Kata right now.

Calling the function through lambda: now matches my Sample Test output with the Test Cases output.
