# Learn String Manipulation by Building a Cipher - Step 16

### Tell us what’s happening:

Describe your issue in detail here.
I am having issues understanding how to convert the sum of index and shift to find a letter in the alphabet string

/* User Editable Region */

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

/* User Editable Region */

Hello Drew,

In step 16, you need to us the alphabet variable to find the character at location index + shift. And store this in a new variable called shifted.

Both shift and index are integers so we can add those to get a single int:

index + shift

Now we would like to find the character in the alphabet that represents this new integer as followed:

alphabet[index + shift]

Then once we’ve done this we would like to assign it to a new variable called shifted.

shifted = alphabet[index + shift]

And there we go, we solved step 16!

You got this!

thank you, this helped a lot. I thought I needed to fully implement the alphabet.find(text) into the line but it was much simplier. Thank you

Haha yeah I ended up wanting to go too fast on occasions too.

hey there @HungryBee

Thank you.

Oh no thanks I’m all good.
Appreciated though.

I must be really tired, I wanted to post this instead

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
