Tell us what’s happening:

I don’t know what i maybe doing wrong

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
        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

First of all, vigenere is already defined, you need to call it.

Then you need to assign the function call to encryption.

I will try it out now. Thank you

def vigenere(text, custom_key):
vigenere()
encryption = vigenere

this is how far i have gone but it is still saying i should have an encryption variable

This is wrong:

vigenere is already defined.
You define a function like this:

def function_name(parameter1, parameter2):
    <code>

You call a function like this:

function_name(argument1, argument2)

To assign the value returned by a function to a variable you do the following:

my_var = function_name(argument1, argument2)
