Hi I`m Heumir I came from Venezuela but I live in Peru and I wanna learn the new language code like Python because I need a real and a very good job. I have few troubles to find wich is a correct coding. I try to put the correct code when told me that: Declare a variable named `shifted`and assign it the`alphabet`letter at`index`plus`shift` . I did it but but that isnt fix can you help me please. Thankyou

``````

Hello Iceman,

You are very close! There are two things. First remember it asks you to use `index + shift` not an integer. For the second one, you may wanna add `shift` inside the brackets. If you keep it out, it will try to add `shift` to the `alphabet` letter at index 7.

ok I do this : shifted = alphabet[index[7]+shift] and this : shifted = alphabet[[7]+shift] and it doesnt work¡¡
what can I do?

Using this one, `index` has the value of 7 already inside it. You don’t need 7 anymore. so just remove `[7]` from this.

Its work¡¡¡ thankyou
