Tell us what’s happening:

Building a Cipher - Step 69

I can’t find my error, i tried search on the internet, even ai like bing, btw i am new here so i would like an comment on the post
Thank you in advance

Your code so far


# User Editable Region

text = 'Hello Zaira'
custom_key = 'python'
direction  =  ''

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)

Add a third parameter called direction to your function definition. Also, comment out the last two lines of code to avoid errors in the console.

these two became a single line so the comments are not recognised, they should still be on two different lines

Thank you again for your response,
Same thing is happening, i am quoting the quote, cause i am stuck, nothing seems to get it through :

text = 'Hello Zaira'
custom_key = 'python'
direction = ''

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.index(char)
            new_index = (index + offset) % len(alphabet)
            encrypted_text += alphabet[new_index]
    
    return encrypted_text
   
#encryption = vigenere (text, custom_key, direction)

#print(encryption)

you are not asked to change these two lines, only to comment them out. direction should not be in there
