Tell us what’s happening:

I have uncommented the last 2 lines of code but not sure how can i pass the call function 1 passing step can anyone help me in this please.

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

Can you see where your function call is? There are 2 arguments at present . You need to add a third one as instructed.
