Tell us what’s happening:

What is the mistake here , I did exactly as told

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

# User Editable Region

        else:
            # Find the right key character to encode
            key_char = key[key_index % len(key)]
            key_index += 1
            offset = 'alphabet.index(key_char)'


# User Editable Region

            index = alphabet.find(char)
            new_index = (index + offset) % len(alphabet)
            encrypted_text += alphabet[new_index]
    print('plain text:', message)
    print('encrypted text:', encrypted_text)

Why are you using quote marks here?

Since, values of variables would have quotes like that, I removed them and It worked

Quotes turn that into a string so they won’t work as a variable anymore.

a = 5
print(a)
>>> 5

print('a')
>>> a
