# Learn String Manipulation by Building a Cipher - Step 16

### Tell us what’s happening:

I struggle understanding what’s going on and what exactly i have to do here. Also I’m not a native speaker, so there might be an additional struggle there - I just might not understand linguisticly what is being demanded. I have noone to ask from my surroundings. And I’m a total zero in coding field.
Please - explain to me what’s the logic of this task codewise. Any help is appreciated!

``````
/* User Editable Region */

text = 'Hello World'
shift = 3
alphabet = 'abcdefghijklmnopqrstuvwxyz'
index = alphabet.find(text[0].lower())
print(index)

shifted = alphabet.find(text[7])+shift

/* User Editable Region */

``````

Learn String Manipulation by Building a Cipher - Step 16

Many people are struggling with this step, it’s being re-written to be more clear.

You made a good attempt! Use this syntax:

`variable = string[var1 + var2]`

You are correct up to this point:

`shifted = alphabet`

Don’t use `find`.

assign it the `alphabet` letter at `index` plus `shift.`

You have the position of H in the `alphabet` string. Now you want to find the letter 3 (stored in `shift`) letters down the alphabet. “Shift” 3 letters along the alphabet to a new letter.
