Learn String Manipulation by Building a Cipher - Step 66

Tell us what’s happening:

What did I do wrong here? Sorry I couldn’t find an available answer that I could understand.

Your code so far

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
            # 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

you do not call a function with def

do you remember how to call a function?

To add to what ilenia mentioned, def is to Define a function, and you only do this once.

When you call the function, the code block that was previously defined will run.

Thank you so much for your help!

Thanks for the suggestion! And just for anyone who stumbles on this thread, to call a function, simply type the function name followed by ()
