Tell us what’s happening:

I don’t know what is wrong with the code. I wrote return statement as the step but it showing errror.

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 * direction) % len(alphabet)
            encrypted_text += alphabet[new_index]

return encrypted_text

Your return statement should be indented four spaces from the function def statement.
