I believe it is better to change 'i' into '_' since 'i' is not used after again.

I'm still new to slicing in python. This solution has a couple great examples. Thank you. I appreciate it.

you will know later to never change the inputs given.incase u need to then make a copy of them

The res variable is unnecessary I think since the signature variable can definitely be used for the tribonnaci operation and for the return with some rejigging

Beautiful. Any suggestions(anyone) on getting better at thinking more like this. Having some mental blocks lately.

bruhhhh why i didnt think like this

TIL theres a built-in sum function.

I'm new to Python...

you guys make me feel stupid lol. that's a great motivation to work harder.

I wish every best solution of every complicated kata had a comment like yours, your spot in heaven is guaranteed bruh

Not efficient.Why should this become "Best Practices"

Man, once you see it, you just feel so stupid.
Good job
