Tell us what’s happening:

It keeps telling me: "Sorry, your code does not pass. Try again.

You should turn the last two lines in your code into comments. Put a # at the beginning of each line."

What am I doing wrong?

Your code so far


# User Editable Region

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

            # 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)

Hi and welcome to the forum :wave:

Add a third parameter called direction to your function definition.

The function definition is denoted by def (define)

This is a function call:

vigenere(text, custom_key, direction)
