Tell us what’s happening:

im pretty sure i did it right but i cant find the answer

Your code so far


# User Editable Region

text = 'Hello Zaira'
custom_key = 'python'

def vigenere(message, key):
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    encrypted_text = ''
    key_index = 0

    for char in message.lower():
        if char == ' ':
            encrypted_text += char
        else:
            index = alphabet.find(char)
            new_index = (index + offset) % len(alphabet)
            encrypted_text += alphabet[new_index]

Hi @

You should declare a variable called key_index at the beginning of your function body.

Try putting the variable declaration at the top of the function body.

Happy coding

You should reload you web page and reset the step 58. When I input your code in its perfectly good for step 58 and 59. If your still having this problem idk whats wrong.
