# Learn String Manipulation by Building a Cipher - Step 16

### Tell us what’s happening:

This is the explanation:

Step 16

As you can see from the output, `"h"` is at index `7` in the `alphabet` string. Now you need to find the letter at index `7` plus the value of `shift`. For that, you can use the addition operator, `+`, in the same way you would use it for a mathematical addition.

Declare a variable named `shifted` and assign it the `alphabet` letter at `index` plus `shift`.

text = ‘Hello World’
shift = 3
alphabet = ‘abcdefghijklmnopqrstuvwxyz’
index = alphabet.find(text[0].lower())
shifted = (index + shift)
print(alphabet[shifted])

The outcome is 'k', which I think is the right ('h' = 7, so 'k' = 10)

Why is my answer not accepted? Thanks for any help!

Hello Ludo,

The outcome is right, but the question wants `shifted` to be the alphabet letter at `index + shift`. Right now `shifted` is literally `index + shift` and then you print the alphabet letter that represents this.

Can you change this so that you can just print ` shifted` and you still get the same outcome?

Ah I see! Thank you!

Please don’t post solution code, thanks!

Roger that, my apologies!
