Wondering how to do this?

I am trying to code a caesar’s cipher
I have this piece of code:

letters = ‘abcdefghijklmnopqrstuvwxyz’

`
and when I try and add a position this happens

position = letters.index(character)

NameError: name ‘character’ is not defined

I expected for it to give me the index of each letter

>Solution :

Is this what you are looking for?

letters = 'abcdefghijklmnopqrstuvwxyz'

for i in letters:
    print(i, letters.index(i))

This will yield an output:

a 0
b 1
c 2
d 3
e 4
f 5
g 6
h 7
i 8
j 9
k 10
l 11
m 12
n 13
o 14
p 15
q 16
r 17
s 18
t 19
u 20
v 21
w 22
x 23
y 24
z 25
