Tell us what’s happening:

Next, inside the else block, declare a variable called key_char and assign it the value of key at the index key_index mod(%) the length of key.

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():

# User Editable Region

        # Append space to the message
        if char == ' ':
            encrypted_text += char
        else:
            key_char = 0

# 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)

Welcome to the forum @anasfalahmo2222

Try assigning the value mentioned in the hint message.

For next time, please Tell us what’s happening in your own words.

Learning to describe problems is hard, but it is an important part of learning how to code.

Also, the more you say, the more we can help!

Happy coding
