Learn String Manipulation by Building a Cipher - Step 69

Tell us what’s happening:

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.
Where is my issue i cant undestand, i’ve try to put 'encryption = vigenere(text, custom_key, dirrection) too but still not working, i think its bug

Your code so far


# User Editable Region

text = 'Hello Zaira'
custom_key = 'python'

def vigenere(message, key, direcction):
    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)
#print(encryption)

I thought that might be the case! Something to watch out for then, variable names need to be exactly as written.

It can help to just copy/paste them to avoid typos or mis-spellings
