Learn String Manipulation by Building a Cipher - Step 81

Tell us what’s happening:

Calling vigenere with 1 to encrypt and -1 to decrypt is fine but it might be a little bit cryptic. Create a new function called encrypt that takes message and key parameters, and use pass to fill the function body.

with these instructions I am trying to figure out if i need to add def before the encrypt=encryption(message, key). Also the pass function is giving me errors no matter where I add it in the code.

I just can’t figure out what I am doing wrong.

Your code so far

text = 'Hello Zaira!'
custom_key = 'python'

def vigenere(message, key, direction=1):
    key_index = 0
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    final_message = ''

    for char in message.lower():

        # Append any non-letter character to the message
        if not char.isalpha():
            final_message += char
            # Find the right key character to encode/decode
            key_char = key[key_index % len(key)]
            key_index += 1

            # Define the offset and the encrypted/decrypted letter
            offset = alphabet.index(key_char)
            index = alphabet.find(char)
            new_index = (index + offset*direction) % len(alphabet)
            final_message += alphabet[new_index]
    return final_message

encrypt = encryption(message,key)

You have several issues here. You declared a variable named encrypt, assigning it the value returned by a function call (but encryption is not a function).

You need to declare a new function named encrypt. How do you do that?
Once you declare the function with the right parameters, you need to add pass to its body.
