True, but this was probably a really old answer. That's why I think Codewars shouldn't obfuscate dates. I don't know how exactly, but I'm sure there's a way to solve the issue of really outdated answers (that were great at the time) being presented as best practices to beginners especially in JS and Python katas.

hey bro you are in all katas 😂😂

It would be more accurate to say that we need to account for 0 as the first number in the sequence, thus we add 1 to generate the expected sequence, not that we exclude zero.

Nice I had the same answer

Use spoiler flag next time, your post was visible in the homepage.

Because factorial is the multiplication of all the numbers from num to 1 whereas sumation is sum of all number from num to 1. Thes question asks for sumation so it is totally unrelated.

because we don't want to include "0", which is generated as a first number

That's...geometric...

your idea of tuple is wrong

tuples are unchangeable

you need to replace tuple with list for the code to work

I think it's because range takes all the numbers up to but not including the 2nd parameter.

For example:
range(1, 8) covers the numbers 1, 2, 3, 4, 5, 6, 7
