Tell us what’s happening:

it says that i have to create an encryption variable
I can’t figure out what to do.

Your code so far

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

    encryption=vigenere(text,custom_key)
    return encryption

You should be calling your function from outside of your function. Also, you should not use a new return keyword

3

thanks it worked. why cant i use return ? i used print and it worked.

4

you can’t use return if you aren’t in a function, and here you need to write outside a function
