Caesar cipher
Apparently, Iâm trying to recreate the Caesar cipher in python. However, the âshiftâ function isnât working. Itâs supposed to add the same key to every letter in the message. (excluding spaces) https://sololearn.com/compiler-playground/c2Iz12HWaez5/?ref=app

If you want to update an element in a list, you must provide the index of the element.
l=list(lst)
for i in l:
if i not in alphabet:
l[i]=" "
continue
else:
l[i]=alphabet.index(i)
In this part of code, the "i" in l[i] is a string...

Welcome back to Python.
There are many caesar cipher code in Code Bits for you to study.
I also created one a month ago (well... Caesar is misspelled in the name...)
As Wilbur Jaywright suggested, using a alphabet variable can save many lines of code and add readability.
And in your code, you forget to handle "space" character which is in your "shift" to-do list.
Maybe this little code helps you recall what you learned.

You didnât indent any code under shift, so the function does nothing.
Also, generally you should not be using more than five or so if statements in a row. You could make this code far more space efficient with an ALPHABET variable set to a string of the alphabet in order, and calling its index method.

I'm replying to the question as OP updated his code and mentioned the "let_to_num" function is not working...

Nice, but I want to break it down into these functions

Also, now the let_to_num function isnât working

Wong Hei Ming please ask that in a new question post, as it does not seem related to this one.

i is holding each character in the message. (including spaces)

Ok, got it
