not neccessarily. python documentation is there for a reason. built in functions are there specifically so you don't have to do the work that's already been done. look up black box and abstractions

true

You probably right, but then again good practice is using built-in functions and not reinventing them

you should use CONST, not LET

I feel like the intent of katas like these are to challenge us NOT to rely on built-ins and really think about how to replicate the behavior of the built-in method. shrug

Old post, i kno, sorry

Isnt it cool that you can think of other ways of doing something other than just the available option already setup?

Ahhh! Thank you for the explanation.

how do you actually read this, I'm so confuse

Just practice. You're in the right place for it. When you complete a kata and you're looking through the solutions, 'test-drive' and take apart/put back together some of the other solutions to see how they work.

facepalm of course it would be something like this. I was trying to avoid using "eval", but was overcomplicating things and finally caved. Simply brilliant
