Your code fails for cases like two_sums([2, 2, 3], 4) as .index only checks the 1st position of that element in the list and not its corresponding position, so for the case above the right index should be 0, 1 but your code checks for .index --> 0 != 0 --> False, so it skips that condition.

debuggin kata is good. at least I get to see how to check others coding.

now that you said it like that, I can relate that with the example given. Much needed help. Thank you

I get you, the description is a little difficult to understand, and staring at the examples don't really help.

Essentially what the description is telling you to do (to encrypt) is to split the string(s) into two groups, one group is the parts of the string at an odd index location, and the other group being the parts of the string at an even index location. Then simply combine these two groups and you have the encryption method.

And you have to repeat this n number of times.
I hope that clears it up for you - and I don't believe anything I wrote here is a spoiler, it's merely a rewriting of the description (people can be a little heavy handed with flagging spoiler content, and that may stop you and others from seeing it if needed).

I thought that at first the question said: every 7 days will have $50 dollar discount. xDD when its just once. like wuuut

I truly dont understand how the encryption actualy being carried out or my brain just out. Is there a better explanation on the encryption process?

whats the standard for variable naming? I just simply used abc and so on for any variable currently. is that bad? or no?

i got value above thousands but still not sure what is it went wrong. need visualiser help to see that i forgot its actualy ^ and not *. whaat a wonderful time waste. hahaha

marvelous coding. needed a visualiser to test this code and see how it works. xDD

yes

took me a while to realise how it works. less variable and straighforward too. i like
