Tell us what’s happening:

Describe your issue in detail here.
So I have made the last two lines that, in the prior step, was to recall a function and then print the results on the following into comments with the # and then I added direction = as the third parameter. Maybe I am wrong, but I thought the error would be that the direction variable does not have any value attached and that is why I cannot progress

Your code so far


/* User Editable Region */

text = 'Hello Zaira'
custom_key = 'python'

def vigenere(message, key):
    key_index = 0
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    encrypted_text = ''
    direction = 

    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)
#print(encryption)

Add a third parameter called direction to your function definition.

Here is your function definition:

def vigenere(message, key):

thank you so much, I misunderstood the question and mistook it for wanting another variable

5

Please which line is the last two line of the code.
Is it the calling function and the print function or its the last two line in the definition block

6

Line 27 + 28.

encryption = vigenere(text, custom_key)
print(encryption)

These call the function, and you are changing the way the function will be called, so they would cause an error.
