Learn String Manipulation by Building a Cipher - Step 68

Python
1

Tell us what’s happening:

I am learning String Manipulation by Building a Cipher, I reached Step 68, and I have tried to solve it and I have spent more than 3 hours, but I could not solve it, so I gave up, please help me instead of resetting the lesson

Your code so far

text = 'Hello Zaira'
custom_key = 'python'

def vigenere(text , custom_key):
    key_index = 0
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    encrypted_text = ''

    for char in message.lower():
    
        # Append space to the message
        if char == ' ':
            encrypted_text += char
        else:        
            # Find the right key character to encode
            key_char = key[key_index % len(key)]
            key_index += 1

            # Define the offset and the encrypted letter
            offset = alphabet.index(key_char)
            index = alphabet.find(char)
            new_index = (index + offset) % len(alphabet)

# User Editable Region

            encrypted_text += alphabet[new_index]

         return encrypted_key
         encryption = vigenere(text, custom_key)

Just FYI when you use the “reset” button it just resets the step you’re on, not the whole project. Feel free to use it whenever you need to.

What you’ve written is correct, but it’s not indented correctly. It’s indented to be part of the function but it needs to be outside/after the function.

Call your function

You would not call your function from inside the function. Well, you would if you want a recursive function, but not in this case.

passing text and custom_key as the arguments

These variables are created outside the function so that’s a clue that you want to be outside the function.

Please, can you help me and write all the algorithm, because I did not know how to do it ?

4

there is no need, you just need to move the line you added outside the function

lol, no.

What you’ve written is correct, but it’s not indented correctly. Just remove the indentation so that it’s at the left, and no longer part of the function.

Indentation to define and call the function should look like this:

def function():
    code
    code
    code

function()

Please let me know if you have any questions

Can someone pls suggest how i can learn how to type fast in a computer?

the best way that I recommend to type faster is to learn touch typing .
get the basic finger positions down then just start typing!
a good sites to practice typing is monkeytype.
