This is the question i am asked to complete "Add a third parameter called direction to your function definition

Python
1 
text = 'Hello Zaira'
custom_key = 'python'

def vigenere(message, key, direction):
    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/decrypted letter based on direction
            offset = alphabet.index(key_char)
            index = alphabet.find(char)
            if direction == 'encrypt':
            new_index = (index + offset) % len(alphabet)
            elif direction == 'decrypt':
                new_index = (index - offset) % len(alphabet)
            encrypted_text += alphabet[new_index]
    
    return encrypted_text
    
# encryption = vigenere(text, custom_key, 'encrypt')
# print(encryption)

everything looks good to me but its not passing

Please post a link to the Step and talk to us about what in the instructions or error message is confusing. Thanks
