Hey there!
Remember that Python is indentation strict.

Python relies on indentation to accomplish its work. Therefore, you should be careful when adding indentation to your code.

Hi, @stephenmutheu

First of all, check tabbing and / or spaces at the beginning of every line:

text[3]
 alphabet.find(text[0]) #<---- check this line

Python is tab/space sensitive (tabs/spaces are used to scope your code).

Then, the exercise: I think you might want to firstly understand what a cipher does or at least this specific cipher. The cipher you are about to design is a Ceasar cipher. The shift is the number of places you have to move forward along the alphabet (your key) to replace the existing letters in your plaintext. The cipher is the function that makes the operations, and that is what you are about to write in python.

Because it is a function, you have to use a def expression somewhere.
