Tell us what’s happening:

I just brought the return function, what us wrong here

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

# User Editable Region

            # 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'

There are two minor issues here:

  1. You should be returning the variable encrypted_text, not the string ‘encrypted_text’.
  2. Your return statement should be indented to the level of the main function. It is indented too far, inside the for loop.
