Tell us what’s happening:

they keep saying that I should put # at each beginning of the line even tho I already done that

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)

Add a third parameter called direction to your function definition.

You still have a little left to do.

[quote=“taha2, post:1, topic:708517”]
# encryption = vigenere(text, custom_key ,direction)
[/quote] do i need to make another function ? because I already added direction as a third parameter

4

You added an argument. Not a parameter.

okay done thanks man
