Tell us what’s happening:

Describe your issue in detail here.
Please which is the last two line of the code? Is it the calling function and the print function or the last two line in the definition block

Your code so far

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
        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, direction)
print(encryption)

decryption = vigenere(text, custom_key)

print(decryption)
I have also added this still not working

Hello Emmaly,

These are indeed the last 2 lines that it asks you to comment. Also, since you are commenting them, you don’t need to add direction to line that calls the function yet.
