Tell us what’s happening:

It says i should have an encryption variable, how do i do that please?

Your code so far


# User Editable Region

text = 'Hello Zaira'
custom_key = 'python'

def vigenere(message, 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)
            encrypted_text += alphabet[new_index]
    
    return encrypted_text
    vigenere(text, custom_key)
    encryption = encrypted_text

You have an encryption variable here. It’s indented to be part of the function, however it comes directly after a return which means it will never, ever execute.

Should i delete the return value please?

5

The instructions don’t mention that, no.

Could you move those lines somewhere that they will execute?

Are they supposed to be part of the function or outside the function?

6

Inside the function, i think

7

Call your function passing text and custom_key as the arguments.

You want to call the function from inside the function? This will create a recursive function, is that what you’re trying to do?
