Describe your issue in detail here.
ok. umm i thought it was right. need help.

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

vigenere(text, custom_key) = encryption
return encryption

If you call the function, it will return a value automatically, as there is a return statement inside the function.
You don’t need a separate return statement.
You should simply declare the variable encryption, assigning the function call as its value.
