Learn String Manipulation by Building a Cipher - Step 63

Tell us what’s happening:

Call your function passing text and custom_key as the arguments. Store the return value of the function call in a variable called encryption .

So that’s what they told me to do.
I don’t know and correct me if I’m wrong. maybe it’s an indentation problem

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]
    encryption = return encrypted_text

/* User Editable Region */

vigenere(text, custom_key)

/* User Editable Region */

That’s part of the task, now it’s need to be assigned to encryption variable.

I found the solution.
you shouldn’t assign “encryption” to the “return encrypted_text”
instead, you should assign the “encryption” variable to the function that you made.
