why am I getting wrong output?

[normal jackal]

Whats the expected output?

[normal jackal]

Can you reshare the code and output as text please?

[thick tree]

let = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']
sen = input()
x=[]
for m in sen:
x.append(m)
for i in x:
if i in let:
try:
x[x.index(i)] = let[let.index(i)+1]
except:
x[x.index(i)] = "a"
for j in x:
print(j,end="")

Hey @thick tree!

It looks like you're trying to paste code into this channel.

Discord has support for Markdown, which allows you to post code with full syntax highlighting. Please use these whenever you paste code, as this helps improve the legibility and makes it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

is this a caesar cipher?

[thick tree]

it is basic cipher

but what is the problem

hello your name is zaher right?
jfnmp bpvu obmf js zaifs siiht?

[normal jackal]

well the first letter should be correct from h to i

>>> let = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']
>>> let.index('h')
7
>>> let[let.index('h')+1]
'i'

[thick tree]

so why it printed j

[normal jackal]

that is strange

Tried with hello world

hello world
ifmmp xpsme

that's correct

But I got the same result as you with your text input

[thick tree]

ya hello world works fine

[muted topaz]

the x[x.index(i)] confuses me

[normal jackal]

ok so I kinda fixed it but... not sure how to explain it.

I'll try my best tho

First of all, don't need to append m to x as its redundant

In fact I removed these lines:

for m in sen:
    x.append(m)

So x is an empty list and what should be done is to loop through the sen sentence by letter

You used i but I set mine to letter so I don't get confused with single character variables

for letter in sen

I then check if letter in let because we have that ? in the sen so that goes into a else: statement and append that in with x.append(letter)

In the if block, we can do the try except and x.append the index of the letter + 1 as shown earlier

like so

try:
  x.append(let(let.index(letter)+1])
except:
  x.append('a')

2 things to notice between your try except and mine

1. I renamed i to letter in the let.index

2. I removed the x[x.index(i)] with simply appending the letter to x with x.append. Keeps it simple

Then after the for loop, I joined the letters into one sentence and check if the result is as expected

result = "".join(x)

Hope that makes sense @thick tree

[thick tree]

Thanks bro that’s really helpful 🤍

I didn’t try your adjustments because I’m out home but it seems logical

[normal jackal]

alright

[thick tree]

But it kinda hurts when there is no idea why the first code not getting expected output

[normal jackal]

a few that I can guess why it didn't work is probably because you were treating the list like a dictionary but it isn't

Like this

x[x.index(i)] = let[let.index(i)+1]

when you should just be x.append it instead

especially this bit x[x.index(i)]

That just doesn't look right
